Congressional Redistricting

Updated 7:45 p.m. ET

In a 5-4 decision along traditional conservative-liberal ideological lines, the Supreme Court ruled that partisan redistricting is a political question — not reviewable by federal courts — and that those courts can't judge if extreme gerrymandering violates the Constitution.

The ruling puts the onus on the legislative branch, and on individual states, to police redistricting efforts.

A high-ranking Census Bureau official privately discussed the citizenship question issue with GOP redistricting strategist Thomas Hofeller in 2015, according to emails cited in a new court filing in the legal battle over the potential census question.

The way Thomas Hofeller talked about redistricting — the drawing of political boundaries and the sifting of voters into buckets — you could be forgiven if you assumed he was speaking about a loved one or a favorite holiday.

The American Civil Liberties Union of Ohio is asking the U.S. Supreme Court to let congressional redistricting procedures proceed. 

Republicans say they will appeal a federal ruling that orders Ohio to draw a new congressional map for the 2020 elections.

A federal court in Michigan says that the state's Republican-controlled legislature unfairly drew some of Michigan's state legislative and U.S. House district lines and that a divided government will have to come up with new boundaries.

A panel of three judges said that 27 of 34 challenged districts diluted the weight of people's votes and that every challenged district is unconstitutional.

The Supreme Court appeared sharply divided on the question of whether there's any limit on what the courts can impose on partisan redistricting, also known as gerrymandering, with Justice Brett Kavanaugh, the newest member of the court, appearing at least somewhat conflicted.

"I took some of your argument in the briefs and the amicus briefs to be that extreme partisan gerrymandering is a real problem for our democracy," Kavanaugh told the lawyers arguing the case, "and I'm not going to dispute that."

Partisan gerrymandering is back at the U.S. Supreme Court.

A year and a pivotal justice's retirement after the high court dodged the question, those seeking to break the political stranglehold over legislative redistricting are urging the justices to draw a line beyond which the Republican and Democratic parties cannot go in entrenching their political power, sometimes for decades at a time.

A three-judge panel of the 6th U.S. Circuit Court of Appeals in Cincinnati has denied a request by the state to delay a federal lawsuit seeking the redrawing of congressional district lines ahead of the 2020 election. 

National Democrats have doubled their spending for state legislative elections in an attempt to chip away at the Republican dominance in state capitols. 

Judges in North Carolina on Tuesday said that despite declaring the state's electoral map to be unconstitutionally gerrymandered for partisan reasons, there wasn't enough time for the map to be redrawn before midterm elections in November.

"We further find that imposing a new schedule for North Carolina's congressional elections would, at this late juncture, unduly interfere with the State's electoral machinery and likely confuse voters and depress turnout," Judges James Wynn Jr., William Osteen Jr. and W. Earl Britt wrote in their order Tuesday.

The U.S. Supreme Court punted Monday on its biggest decision of its term so far. The justices had been expected to rule on the limits of partisan gerrymandering.

Instead, the court sidestepped the major issues on technical grounds, sending the issue back to the lower courts for further examination.

The Ohio Ballot Board has approved placing before voters in May a congressional redistricting plan.

Even as Democrats and Republicans spend 2018 vying to win key races around the country, a larger legal battle underway this year could reshape the American political map — literally.

By June, the U.S. Supreme Court is likely to decide three major redistricting cases — out of Wisconsin, Maryland and Texas — that will lay some of the foundation for what the maps will look like, not just this year, but after the 2020 census that could affect control of Congress for the next decade.

The state of those legal cases and other key ones (that could affect 2018 and 2020) are below.
