While the president has seen his approval ratings plummet, the outlook for other Democrats isn't nearly as bad – and has even been looking up ahead of the midterms. SCOTUS' overturning of Roe v. Wade, and extremist Trump-like candidates running for the GOP have given Democratic voters a reason to get out and vote.
Democrats are running against history, as the party in power almost always loses ground in Congress in midterm elections. With Biden's approval ratings remaining low, if the Republicans focus on rampant inflation, crime, and the economy, the GOP can certainly win the House and possibly the Senate, too.
There's a 41% chance that the Republican party will control both the House and the Senate after the 2022 midterm elections, according to the Metaculus prediction community.
