So, the 3 opponents who split 33% of the vote to Graham's 67% would have somehow done better if there were only one? In fact, he outdid his previous primary result by 10% and received over 110,000 more votes than 2014. It would seem Graham is pretty popular with SC voters, and they have no desire to replace him...
Everyone they elect to Washington is a Cheap Labor Express stooge, I guess they like their state overrun with illegal aliens.
