Trump tests and looming battleground races highlight Tuesday's primaries

President Donald Trump's endorsement will once again be put to the test in multiple Republican primaries Tuesday, which will also mark the kickoff of major general election campaigns for Senate and governor in battleground Georgia.

Voters head to the polls for primaries in Oklahoma, as well as the District of Columbia, where the battle for mayor has highlighted broader divides in the Democratic Party. And Alabama and Georgia are holding primary runoffs in races where no candidate won a majority of the primary vote May 19.

In California, voters in the 14th Congressional District will weigh in on a replacement for former Democratic Rep. Eric Swalwell, though this special primary election could lead to a special general election in August if no candidate wins a majority of Tuesday's all-party vote.

Here are the key races to watch Tuesday:

Trump's Georgia picks

Trump made a last-minute endorsement in the Republican Senate runoff in Georgia, backing GOP Rep. Mike Collins in the very early hours of Sunday. Collins is facing former football coach Derek Dooley, and the winner will face Democratic Sen. Jon Ossoff in November in a race that will be central to the battle for the Senate.
