A series of polls released Sunday and Monday show Democrats heading into Tuesday's midterm elections with a lead over Republicans, but how much of a lead depends on the source. An NBC News/Wall Street Journal poll shows Democrats ahead by 7 percentage points, while a CNN poll measuring which party voters want to control Congress shows Democrats with a 13-point lead. As Democrats and Republicans travel their districts making their final pushes, President Trump is maintaining his heavy campaign schedule, heading to Missouri on Monday for a rally with Fox News host Sean Hannity and fellow conservative pundit Rush Limbaugh. Democrats are forecast to flip the House and Republicans are expected to keep control of the Senate, but after state-level polling errors in 2016, nothing feels certain.
