According to multiple media sources, the DSCC has stopped advertising in Kentucky and has not reserved any time between now an election day. This news comes at the worst possible time for Alison Grimes. For the past five days, she's had to deal with the fallout from her non-answer as to whether she voted for Obama. In today's White House press briefing, national reporters and Josh Earnest laughed at Grimes' contention about right to privacy and the sanctity of the ballot box.
If you check my comment history, I wrote this past summer why I thought it was highly unlikely Grimes would defeat McConnell. Obama's low popularity and the sixth year itch aside, the changing voting patterns of eastern KY made it more than a little daunting for her to make up the difference with huge showings in Louisville and Lexington. And just yesterday, local black leaders in west Louisville said Grimes' refusal to say whether she voted for Obama could depress turnout in predominantly black areas.
Having said all that, don't look for a blowout win by McConnell unless Grimes commits another self inflicted wound. McConnell's own low popularity remains a drag for him. The best guess, and I have spoken to a lobbyist or two in the area who work the halls of Frankfort, is McConnell wins by 4-6 points. In fact, many in Frankfort have placed the over/under at 5 points.
