(Reuters) -Scores of posts on Twitter and Facebook challenged Democratic successes in U.S. midterm elections without evidence on Wednesday, social media experts said, but the misinformation did not rise to the firestorm levels that followed President Joe Biden's victory in 2020.

Researchers who study misinformation are closely monitoring online discussion following Tuesday's voting, which will decide control of Congress. False narratives about fraud during the 2020 presidential race, promoted by then-President Donald Trump on Twitter, fueled a deadly siege of the Capitol. Trump was later banned from the social media service.
