Former President Obama caps a five-state tour aimed at stemming his party's losses in Tuesday's congressional elections with appearances in Pittsburgh alongside Democratic Senate nominee John Fetterman before heading to Philadelphia, where he will take the stage at Temple University with President Biden. Former President Trump, meanwhile, will be ginning up support for his hand-picked Republican Senate nominee, celebrity doctor Mehmet Oz, and Republican gubernatorial nominee Doug Mastriano at a rally in Latrobe, southeast of Pittsburgh. Nonpartisan election forecasters and polls show Republicans are heavy favorites to win control of the House of Representatives, with the Senate a toss-up. Control of even one of those chambers would give Republicans the power to block Biden's legislative agenda and launch potentially damaging investigations. At a debate last month, he often stumbled over his words, in a performance even allies privately described as shaky.
