Fact-checking the North Carolina Senate race

Fact-checking the North Carolina Senate race-politico: The North Carolina Senate race pits incumbent Democratic Sen. Kay Hagan against Republican challenger Thom Tillis. While the two campaigns have aggressively attacked each another, they’ve had a lot of help from outside supporters as well. So far, the race has attracted at least $37 million in spending by outside groups, the most of any fall contest, according to a Sunlight Foundation analysis of Federal Election Commission data. Of that amount, more than $25 million has been spent on attack ads — more than $6.5 million against Hagan and nearly $19 million opposing Tillis.
