Midterm election updates: Cook Political Report shifts two races toward Democrats and one toward Republicans

President Donald Trump continues to rally Republicans with a stop in North Carolina tonight, hoping to boost voter turnout and support for Republican Senate candidate Michael Whatley.

John Sununu, the Republican Senate candidate from New Hampshire, has distanced himself from Trump in a new television ad, even though he has the president’s endorsement. Meanwhile, this year’s midterm elections are poised to break advertising spending records, with more than $11 billion projected for Election Day.
