The nomination fight over Judge Brett Kavanaugh has injected new volatility into the midterm elections, reshaping races across the United States and sharpening the already bitterly partisan tone for the final four-week stretch before voters go to the polls on November 7.
Much uncertainty remains - not least because of the rapid-fire succession of evolving crises that have marked President Donald Trump's term in office - but for now the weeks-long Kavanaugh saga appears to be pushing House races toward Democrats, even as it has given Republicans better odds of maintaining control of the Senate.
That division stems from the make-up of the races and the political geography of the most competitive battles. House contests this year already were expected to be determined by suburban women, who had pulled away from the President over his term in the White House and appear to be the most sympathetic to Christine Blasey Ford, the woman who testified that Kavanaugh had assaulted her when both were teenagers.
But most of this year's competitive Senate races are in traditionally red states, and as Republicans have rallied to Kavanaugh's side, the chances of Democratic upsets there have dropped, at least for now.
