RALEIGH -- Going into Tuesday's election, many polls had Incumbent Democratic Sen. Kay Hagan with a slight lead, although still within the margin of error. But, as we know now, Republican Thom Tillis took the race by a little over 1%. John Hood, with the conservative John Locke Foundation, says last-minute-undecided voters broke for Tillis.

Hood said, "Really, unpopular means that the disapproval rating is much higher than the approval rating. Then you can expect at the end of the day, you're final group of undecided votes - if they show up - are going to break about 2-to-1 against the incumbent. Even if they don't like the challenger very much, they're going to break that way. And, that's what happened to Kay Hagan this year."

He says there were some polls that had Tillis slightly head, but they were discounted.
