United States President Donald Trump has raised questions about the integrity of last week's midterm elections, a departure from his earlier statements congratulating Democrats on their victories. On Monday, Trump posted on Truth Social, expressing doubts about the election's honesty and questioning why polls were so inaccurate. Despite Republicans' claims of underestimated support in past elections, the results showed a strong night for Democrats. Pew Research found that pre-election polling data understated the Democratic margin by at least 2 points in 23 out of 27 races. Trump also accused some early voting ballot counts of being so large they made it impossible for Republicans to win, without providing any evidence of fraud or wrongdoing. This is Trump's first public challenge to the overall midterm results since Democrats overwhelmingly won control of both chambers of Congress and took victories in traditionally Republican strongholds. Democratic Senate leader Chuck Schumer criticized Trump's claims as a return to baseless election denialism, saying it was inevitable given Trump's unprecedented failure during his presidency. Republicans have been distancing themselves from Trump following their midterm losses, with even conservative commentator Megyn Kelly urging him to stop making unfounded fraud claims.
