Democrats in mourning over Donald Trump’s victory can comfort themselves with the fact that, if the United States follows the pattern of other democracies that elect wannabe strongmen, their party should have a very good chance to win back the White House in 2028. The same cannot be said for the United States Senate.
With very few votes left to count in last week’s election, the Republican Party appears to have flipped four Senate seats—in Pennsylvania, Ohio, West Virginia, and Montana—giving it a presumptive 53–47 majority. On the surface, that outcome may not seem dramatic, and in fact represents a fine performance for Democrats. The party had no realistic pickup opportunities this election cycle. Meanwhile, it had to defend three seats in red states and five seats in swing states. Democratic incumbents lost all the red-state races, but won four of the five purple-state contests: in Arizona, Nevada, Wisconsin, and Michigan—all states that voted for Trump.
The real problem for Democrats is that the 2024 map was only slightly harsher than usual. Going forward, every Senate election is going to be brutal. The institution is so skewed in favor of the current Republican coalition that Democrats need at least a few red-state seats to win consistent majorities. Now they have none.
The partisan divide of the 50 states is not an immutable fact of nature, but here’s how things look for the foreseeable future: 24 states are solidly red; 17 are solidly blue. Over the past three presidential cycles, only six states have swung back and forth: Pennsylvania, Michigan, Wisconsin, Georgia, Arizona, and Nevada. Throw in New Hampshire, North Carolina, and Minnesota—where Trump or Kamala Harris won by about four points or less—and America has nine purple states in total, representing 18 Senate seats. To hold the chamber, Republicans need to win just two of those seats if they control the presidency, and three if they don’t. Democrats need to sweep almost all of them. They must pitch perfect game after perfect game to have a shot at even the narrowest majorities.
And even a perfect game will not be enough in the 2026 midterms. That year’s map features just two realistic pickup opportunities: Maine and North Carolina. Democrats, meanwhile, will need to defend seats in Georgia, Michigan, New Hampshire, and Minnesota. Unless they pull off a major upset, they can at most cut the GOP majority to 51. In that best-case scenario, they will then need to flip either North Carolina or Wisconsin in 2028 without losing seats in Georgia, Pennsylvania, Nevada, Arizona, or New Hampshire. Barring any unexpected deaths or retirements, Democrats can afford to lose only one swing-seat race over the next four years to have a shot at 50 senators.
Anything short of that means that, even if a Democrat retakes the White House in 2028, that president will be immediately hamstrung. Even a narrow GOP majority will make it impossible for, say, President Josh Shapiro or Gretchen Whitmer to pass liberal legislation. They would instead, from the moment they’re sworn in, have to contend with congressional investigations, government shutdowns, and debt-ceiling hostage negotiations.
Their troubles would hardly end there. A GOP Senate majority would slow-walk or even block a Democratic president’s Cabinet nominations and personnel appointments. An administration without administrators would be unable to issue new regulations and rules. Whatever policies the administration did manage to make would then be tied up by an ever more hostile judiciary. Without control of the Senate, Democratic presidents will struggle to get nominees confirmed at even the district and circuit levels. They can forget about the Supreme Court.
Democrats have been aware of their Senate problem for years. That’s why, during the first Trump term, many liberals urged the party to prioritize scrapping the filibuster and making Washington, D.C., and Puerto Rico states as soon as it had the opportunity. But the opportunity never truly arrived, because the Democrats’ brief trifecta under Joe Biden depended on moderate senators, such as Joe Manchin and Kyrsten Sinema, who refused to entertain any such hardball tactics. Addressing the Democrats’ Senate problem legislatively would appear to require a more substantial Democratic Senate majority, which is precisely the issue.
And so, if they are to expand their options in the Senate, Democrats will have to find some way to broaden their appeal in the states where voters seem to have irrevocably abandoned them. That is not a new idea, and it is not an idea that anyone has yet figured out how to implement. But it is the only option. If Democrats don’t figure out how to compete in more states, Trump and his allies won’t need to dismantle the free press, imprison their enemies, or overturn election results to ensure perpetual GOP dominance. The basic math of the Senate will do that for them.
