Primary voters on Tuesday will decide the fate of two South Carolina Republicans who are clinging to their seats in the U.S. House after defying Donald Trump, while in Nevada an establishment favorite with the former president's endorsement is facing a tougher than expected challenge for the U.S. Senate.
Meanwhile, in Maine, a bellicose former governor who once said he was “Trump before Trump” has come out of retirement in Florida to challenge a nemesis for his old job.
