President Donald Trump issued a call over the summer for Republican-led states to consider redrawing their respective congressional district maps to gain additional seats for the GOP in the 2026 midterm elections, and Texas was the first to accomplish that feat last month.

Texas has now been joined by Missouri, which just passed newly redistricted maps through its Republican-controlled House and Senate this past week, according to the Daily Caller.

The legislation, which is expected to be signed into law soon by Republican Gov. Mike Kehoe, will likely transform a long-held Democratic district in the Kansas City area into one that a GOP candidate could more easily win.

New map passed by the legislature

When Gov. Kehoe first called for a special legislative session last month, he made congressional redistricting a top priority on the agenda. He even introduced a proposal drafted by his team that was dubbed the "Missouri First Map."

"Missourians are more alike than we are different, and our Missouri values, across both sides of the aisle, are closer to each other than those of the extreme Left representation of New York, California, and Illinois," the governor said at the time. "Missouri’s conservative, common-sense values should be truly represented at all levels of government, and the Missouri First Map delivers just that."

That GOP-favorable map was subsequently voted on and approved by Missouri's Republican-led House and Senate, and now awaits only the governor's signature to become law.

"The Missouri FIRST Map has officially passed the Missouri Senate and is now headed to my desk, where we will review the legislation and sign it into law soon," Kehoe said on Friday in an X post.

Democrats outraged, vow legal challenges

Of course, not everybody is happy about the newly redrawn district map, most notably Rep. Emmanuel Cleaver (D-MO), whose previously mostly urban Kansas City-area district has now been redone to include some of the surrounding rural area, likely making it easier for Republicans to win.

The new map also reportedly strengthens another district already held by Republicans in a way that will almost guarantee that it remains in the GOP column, per the Daily Caller.

Cleaver, who has served in Congress for 11 terms, or more than 20 years, has denounced the redistricting plan as "stinky" and vowed to fight against it in court.

Other states could soon redraw their maps

As noted, Texas was the first state to pass an unusual but not illegal mid-decade redistricting plan, which has the potential to shift five congressional seats from the Democrats to the Republicans, and they've now been joined by Missouri, which will likely pick up one additional GOP seat in the next election cycle.

Meanwhile, in a bid to cancel out the gains made by Texas, California's Democrat-dominated legislature passed its own redistricting plan that, if approved by voters in a special election in November, could result in five Republican seats being shifted over to the Democratic column next year.

Those states may not be alone for long, though, as The Hill reported that several other states are now considering launching redistricting efforts of their own, including on the Republican side, Florida, Indiana, Kansas, Nebraska, and Ohio, each of which could add at least one more GOP seat, if not as many as three to four more, in the case of Florida and Ohio.

On the other side of the partisan ledger are Democrat-led states like Illinois and Maryland, which have similarly vowed to redraw their districts to eliminate some or all of the few Republican seats they have, but those states are already so heavily gerrymandered in favor of the Democrats that it is unclear how much, if any, progress they could make toward their anti-GOP goals.
