Senate Guru says Kay Hagan is a contender:
Given that Dole is presumably at maximum name ID and that she rarely touches 50% in any approval poll (that isn't commissioned by her campaign or her partisans), she has little room to grow. On the other hand, Hagan is still expanding her name ID beyond her State Senate district. And polling indicates that her paid media campaign is incredibly effective. This won't turn into a Tier 1 race overnight, but every indication is that this is a strong Tier 2 race with much potential.
Hagan's going to need national money to win this thing.
