Representative democracyis a beautiful matter , but the cognitive operation of make the lines for congressional and state legislative districts can get ugly .

TheConstitutionis vague on how vote districts should be drawn , tell onlythat they should be updated every 10 class and be roughly equal in population . Over the 100 , American politicians have seized on the once - a - 10 redistricting cognitive operation to redraw vote maps to their advantage . While partisan redistricting is an accept if bemoaned practice , the court of law have find oneself it unacceptable to redraw voting districts for the express purpose of suppressing the voting power of Black elector and other racial minority radical .

Gerrymandering is the use of voting dominion for hyper - partizan or racist reasons , but the phone line between legit redistricting and unethical gerrymandering is blurry at best . It ’s ultimately up to judge to decide whether a redistricting design is kosher or not .

Quick Primer on Voting Districts

Every 10 years , the United States conducts acensus . The inbuilt purpose of the census is " parcelling , " the process of determining how many seats each state should have in the House of Representatives . While the Constitution automatically allots two senators for every res publica , the apportioning of representative in the 435 - seat House is based on universe , with thickly settled states like California getting 52 representatives ( as of the 2020 nose count ) and sparsely populated states like Wyoming and South Dakota only father one seat each .

Members of the House are voted into post by the elector in their congressional district back home , and according to the Constitution , those districts should each be approximately the same size , mean that each of the 435 House appendage represent roughly the same number of people . Theaverage congressional districtnow holds 761,169 people . The same is rightful for State Department general assembly . Both state senators and state house members present specific voting district that are separate every bit among the state ’s population .

Who draw the district maps ? A handful of United States Department of State appoint independent commission to draw in their district lines , but those are the outliers . in good order now , state legislatures in 39 states draw their own congressional dominion , including the six states that only have one congressional district . And it ’s a similar story for state - degree voting territory , where 34 state legislatures have full ascendency of the mental process .

If the state general assembly is hard in the hand of one political political party — as it is inmore than halfof all states — then that political party drill a lot of ascendence over the redistricting process . By tweak the size and shape of voting districts , they can boost the vote king of their party and increase the betting odds of win congressional and state legislative tush .

But when does partizan redistricting cross the line and become illegal gerrymandering ?

The Rules of Redistricting

When state legislators sit down to redraw their voting district maps , even in solidly Republican or popular states , they are expect to toy by some canonical rules , saysDoug Spencer , a jurisprudence prof and election law assimilator at the University of Colorado Boulder :

Of those three characteristics , the tightness ( or non - compactness ) of a dominion is ordinarily the one that triggers accusations ofgerrymandering , says Spencer , who also make do the websiteAll About Redistricting . " If you see a bizarrely mold district , that lift your antennae that it may not have been drawn neutrally , but in a elbow room that favors some group : a political group , a racial grouping or something else . "

After all , it was thefreakish shapeof a Massachusetts congressional territory that helped coin the terminus " gerrymander " in 1812 . The long and snaking dominion was sanction by Gov. Elbridge Gerry and delivered a hefty electoral advantage to his political party , the Democratic - Republicans . A paper cartoonist note the salamander - corresponding shape of the district and labeled it " the Gerry - mander " after its partisan creator .

Partisanship Alone Isn’t Illegal

According to Spencer , the court have recognized that partisanship in the redistricting cognitive process is an take on outcome of state elections . If voters put ascendancy of the state legislative assembly in the hands of one party , then there is an arithmetic mean that party functionary will make redistricting decisions that benefit their company .

" The question becomes , how much partiality is too much ? " says Spencer . " That ’s a line of business that ’s hard to tell apart . "

Some state general assembly are blatantly honorable about what they are endeavor to achieve with redistricting efforts . In North Carolina , the Republican chair of the land ’s redistricting committeesaidin 2016 , " I propose we draw the maps to give an vantage to 10 Republicans and 3 Democrats , because I do not believe it is potential to attract a map with 11 Republicans and 2 Democrats . " And in Maryland , the Democratic governortestifiedthat a newfangled district was drawn to " make a district where the hoi polloi would be more probable to elect a Democrat than a Republican , yes , this was clear my intent . "

Do such statements go too far ? For its part , the Supreme Court is keeping out of the controversy . In 2019 , the justice ruled 5 - 4 that the nation ’s highest court wouldnot get involvedin challenge to state redistricting plans on stringently political grounds . They left those challenges to land lawmakers and commonwealth court .

Racial Gerrymandering Is Still Outlawed

Racially motivated gerrymandering is unconstitutional under the 14th Amendment guarantee of adequate protective covering under the legal philosophy . But before the 1964 Voting Rights Act was fall out , state legislatures in the Jim Crow - era South used a pair of gerrymandering tactics to strip Black voter of equal electoral power : packing and cracking .

" It was a strategical choice , " says Spencer . If smutty voters were concentrate in certain geographical areas of a state , then the legislator would " compact " them into one or two dominion . Even if that make substantial Black voting block in those territory , their vote would be outweighed by all of the majority - white districts .

If Black voters were more geographically dispersed , then the districts were take up in ordering to " check " or dilute the Black right to vote by assign minor routine of Black voters to several different districts . In that way , their part were guarantee to be drown out by the white majority .

That was think to change with the Voting Rights Act , which let in a provision that six southerly states had to receive Union approval for their redistricting plans . Those six province — Alabama , Georgia , Louisiana , Mississippi , South Carolina and Virginia — were flagged for extra scrutiny because of a history of race - based gerrymandering . In the seventies , three more country were add together : Alaska , Arizona and Texas .

But in a landmark 2013 causa , the Supreme Court " bailed out " those nine state from having to seek congressional preapproval for their redistricting plans , stoke fears of a unexampled wave of racially motivated gerrymandering in Republican - controlled Southern legislatures .

" In [ the 2021 - 22 ] bike , for the first time since the sixties , state legislatures can redistrict without getting their architectural plan review and okay by the Union government , " allege Spencer .

When Courts Step In

The reality is that racial gerrymandering is still unlawful and can be challenge in both state and federal royal court . A lawsuit intended to block a commonwealth ’s redistricting plan on racial grounds must be filed by a voter of color live in the district , read Spencer , not an external political governance . It ’s then up to a judge or Book of Judges to limit if there ’s enough evidence to conclude that the dominion line were , in fact , drawn to disenfranchise nonage voters .

" The judge ’s caper is to valuate the grounds — testimonies , emails and text between lawgiver , etc . — to suss out if the redistricting decision were merely partizan , which is provide , or was in reality about race , " says Spencer .

There were two high-pitched - profile Supreme Court case in late years in which redistricting architectural plan were reject on grounds of racial gerrymandering :

What puddle the course between redistricting and gerrymander so blurry is that the electorate has become increasingly polarize along racial credit line , says Spencer . In the 2020 presidential election,92 percentage of Black voterschose the Democratic prospect , Joe Biden . Meanwhile , white voters go forward to skew Republican in 2020 , peculiarly non - college - cultivate Theodore Harold White , 65 per centum of whom vote for Donald Trump . What that intend for Republican - held legislatures , especially in the South , is that any attempt to check or pack popular dominion risks aim Black voters .
