Democratic Rep. Steve Cohen announced Friday that he will not seek reelection to the Tennessee seat he has held for nearly two decades, citing a newly drawn congressional map that carved up his majority-Black Memphis district and, in his words, left it looking "nothing" like the one he represented.
The 19-year incumbent's exit marks the latest casualty of a redistricting wave that has handed Republicans fresh advantages across the South, and stripped Democrats of seats they once considered safe.
Tennessee lawmakers passed a new congressional map that splits Memphis along new lines and eliminates the Democratic advantage in the state's 9th District. The map places just 31 percent of Black voters in one of three districts carved from Shelby County, the Daily Caller reported. Cohen, who was first elected to the House in November 2006 and sworn in on January 3, 2007, called the moment the most difficult of his career in public office.
At a news conference, Cohen laid the blame squarely on state Republican lawmakers who approved the new lines. He told reporters:
"This district that they have on the new lines is nothing like the 9th district that I've represented. I've had the great honor of representing the 9th district for the past 19-and-a-half years, and it's been a district that's been a majority African American district."
Cohen went further in remarks reported by Newsmax, saying plainly: "I don't want to quit. I'm not a quitter. But these districts were drawn to beat me."
That framing, that the map was engineered to end his career, is worth examining. Tennessee is a deep-red state. Republicans hold supermajorities in the state legislature. The 9th District, anchored in Memphis, was the only Democratic-majority congressional seat in the state. Now it no longer exists in its previous form.
Whether you call that gerrymandering or the legitimate exercise of a state legislature's redistricting authority depends on your vantage point. What is not in dispute is the result: Cohen saw the math and walked away.
Cohen's departure does not stand alone. Republican-led state legislatures across the South have moved aggressively to redraw congressional maps, and the numbers tell the story.
Florida passed a new map on May 4 that handed Republicans four additional seats. In Texas, redistricting efforts could deliver up to five new GOP seats. Missouri and North Carolina have also enacted maps expected to give Republicans an advantage.
The U.S. Supreme Court cleared the way for Alabama to use its 2023 congressional map, which included only one majority-Black district. And on May 8, the Virginia Supreme Court struck down state Democrats' gerrymandering referendum, a measure that had been designed to give Democrats four additional seats.
Florida's map alone represents a significant shift in the House landscape. Taken together, these redistricting battles could reshape the balance of power in Washington for the rest of the decade.
Democrats have cried foul at every turn, but the legal and political terrain has shifted under their feet. The Supreme Court's recent rulings have narrowed the grounds on which redistricting plans can be challenged, and Republican state legislatures have moved quickly to capitalize.
The Tennessee map vote was not unanimous even among Republicans. State Reps. John Gillespie and Mark White broke ranks and voted "no" alongside Democrats. Three other Republicans, Reps. Michele Reneau, Ron Travis, and Greg Vital, voted "present," a move that signals discomfort without outright opposition.
That five Republican lawmakers either opposed or declined to support their own party's map suggests the new lines generated internal friction. But the map passed nonetheless, and the political consequences followed swiftly.
Cohen, for his part, has not entirely closed the door. Newsmax reported that he is challenging the new map in court and said he would reenter the race if his former district is restored. That contingency feels more like a face-saving gesture than a realistic path back, given the current legal climate around redistricting challenges.
House Democratic leader Hakeem Jeffries praised Cohen in the wake of his announcement. "He was a powerful champion for civil rights," Jeffries said. The tribute was gracious but also underscored the party's predicament: Democrats are losing veteran incumbents in districts that no longer exist as they once did.
The broader question for Democrats is whether they have any effective counter-strategy. In Virginia, their attempt to lock in favorable maps through a ballot referendum was struck down by the state's Supreme Court. In the South, they are watching one majority-minority district after another get redrawn or diluted.
Republicans, meanwhile, are using the tools of state government exactly as the Constitution envisions, state legislatures drawing their own congressional maps. That process has always been political. The difference now is that the legal guardrails Democrats relied on for decades have been loosened by the courts.
Cohen's decision not to run again effectively concedes that Tennessee will send an all-Republican delegation to Congress. For a state that gave Donald Trump commanding margins in both 2020 and 2024, that outcome reflects the underlying political reality more accurately than the old map did.
The 9th District, as Cohen knew it, was a product of a different era of redistricting law, one that prioritized the creation of majority-minority districts. The new map reflects a legislature's judgment that Shelby County's voters can be represented across multiple districts rather than concentrated in one.
Critics will call it voter dilution. Supporters will call it competitive redistricting. The internal dynamics of the House Democratic caucus are already under strain from members breaking with leadership on key votes, and losing a 19-year veteran like Cohen only adds to the pressure.
Several open questions remain. Cohen has not said whether he would run in a different district. The exact boundaries of the newly drawn 9th District have not been widely detailed. And the outcome of his court challenge, while unlikely to succeed given the current legal landscape, could still produce a ruling with implications beyond Tennessee.
For now, the facts are straightforward. Tennessee's Republican legislature redrew the map. Cohen looked at the new lines, did the math, and stepped aside. Democrats lost a seat, and the trend line suggests more losses are coming.
Elections have consequences. So does winning state legislatures.
