Democrats dropped the ball. It's literally the job of the candidate to properly vet their opponent.
These days all the candidate needs is an R or a D in front of their name to get registered party members to vote for them.
Democrats kind of fucked themselves on this one, now it opens the door to their lying politicians. Republicans need to ride this out until democrat "blood" is drawn.
(not literal blood, wouldn't want Seran to poop his pants.)
