Tuesday’s elections include a pair of Senate runoffs that will test the power of President Donald Trump’s endorsement in a Republican primary.

In battleground Georgia, two-term Rep. Mike Collins, who picked up the president’s backing over the weekend, faces former football coach Derek Dooley in the race to take on Democratic Sen. Jon Ossoff.
