He most likely will. The dems will engineer "wins" in these close races.
My guess is McConnell will win. He is now ahead in the polls.
McConnell has never been very popular in KY.
But BHO and Harry Reid are even less so in that state.
The McConnell campaign will accurately portray Grimes as a proxy for both BHO and Reid which is all it really needs to do to win.
