Take these with a grain of salt, but a good pollster tells me that an exit poll conducted earlier today showed Republican Thom Tillis and Democratic senator Kay Hagan neck-and-neck in North Carolina.

In New Hampshire, Scott Brown trailed Democratic senator Jeanne Shaheen by a few points.

Exit polls can be unreliable, but, traditionally, they improve for Republicans throughout the day, the pollster said, because GOP voters tend not to be home earlier in the day.
