The previous poll by Survey USA gave Bunning a 24-point lead. now it's down to 11.
Though I don't live in Kentucky, I get Kentucky news. Bunning has committed some gaffes and the media there has given it extensive coverage. And ads attacking Bunning and plugging Mongiardo are on the air, the first time this year this has happened.
This race is no longer a sure thing.
This poll, if you look at the dates, was also taken before the gaffes that got the extensive media coverage.
