In a state that’s home to a large number of military installations and veterans, the supercharged showdown between two candidates who’ve been sparring for months could play big, potentially reordering the race in the final week.

Our Principles PAC, launched last month with the purpose of attacking Trump, is preparing to blanket South Carolina’s airwaves with a new ad featuring Trump’s past statement that impeaching George W. Bush “would have been a good thing.”
