Redistricting legislation begins test in Indiana state Senate

A proposal to redraw Indiana's congressional boundaries faces its first public test in the state Senate on Monday, with no clarity on whether it can pass a final vote later in the week despite months of pressure from President Donald Trump.

Senators will take action on a bill designed to favor GOP candidates in the upcoming midterm elections. However, many Republicans, who control the chamber, have been hesitant or even outright opposed to the idea of mid-decade redistricting. Several have also been threatened over their opposition or unwillingness to immediately declare support.

Their deciding votes could test Trump's typically iron grip on the Republican Party. Monday's expected committee hearing could give a first glimpse at how many senators plan to go on record against the bid to consolidate power in the staunchly conservative state.

The map introduced just last Monday and passed by the Republican super majority in the state House on Friday splits the city of Indianapolis into four districts, distributed across other Republican-leaning areas. It also groups the cities of East Chicago and Gary with a wide swath of rural counties in northern Indiana.

The contours would eliminate the districts of the state's two Democratic congressional representatives: longtime Rep. André Carson, representing Indianapolis, and Rep. Frank Mrvan, representing northwest Indiana near Chicago. Carson is the state's only Black member of Congress.

Republicans currently hold seven of the state's nine districts.

Democrats are hoping to flip control of the U.S. House in the 2026 elections and like their odds, since midterms tend to favor the party opposite the one in power.

Redistricting is typically done once a decade following the census. But Trump has pushed Republican-led states to squeeze out more districts winnable for Republicans as a result. Texas, Missouri, Ohio and North Carolina have followed suit, while Democrats in California and Virginia have moved to draw their own favorable districts in response.

But the idea of redrawing a congressional map last approved in 2021 has made many Republicans in Indiana uneasy, particularly in the Senate. The leader of the state Senate previously said there were not enough votes in support of redistricting. But where the vote count stands going into Monday is unknown.

Senators are scheduled to meet on the floor at 12:30 p.m., and the Senate elections committee is scheduled to meet at 1:30 p.m.

The White House has upped the pressure on Indiana. Vice President JD Vance visited Indianapolis twice since August, and legislative leaders met with Trump in the Oval Office earlier this year.

After the leader of the state Senate, Republican Rodric Bray, said the chamber would reject the governor's call for a special session on redistricting, Trump repeatedly lashed out at Bray and other state Senators on social media. Trump promised to endorse primary challengers to any state lawmaker who opposes redistricting.

In the weeks following, about a dozen state lawmakers were the victims of threats and swatting, in which a hoax call is made to police to elicit a law enforcement response, typically to someone's home.

In the 50-person Senate chamber, redistricting proponents need at least 25 “yes” votes to give final passage to the map. That would trigger a tiebreaking vote from Republican Lt. Gov. Micah Beckwith, who is in favor of redistricting.

If the Senate were to vote against the new map, it would be extremely difficult for proponents to try again. The deadline to file to run for Congress in Indiana is in early February, and primary elections are held in early May.
