STORY: Democratic challenger Alison Lundergan Grimes has cast her vote in the Kentucky Senate race in a bid to unseat Republican Senate Leader Mitch McConnell.

Polls show McConnell has a slight edge over Grimes. If McConnell hangs on for re-election, and Republicans win control of the Senate he would replace Democrat Harry Reid as Senate majority leader.
