It is the Lexington Herald-Leader / WKYT Bluegrass Poll that interviewed 1,082 registered voters in Kentucky. The poll had a margin of error of 3 points. The results of the survey are illustrated in the charts above, which show Grimes with a 4 point lead over McConnell (46% to 42%). The second chart shows where McConnell's biggest problems are -- with women, moderates, young voters, and seniors (a real bad sign since seniors generally support GOP candidates).
This is almost unheard of, since party leaders like McConnell seldom have any problem getting re-elected. And while he may still survive this challenge, this poll (just like the many others) shows that McConnell has a fight on his hands. McConnell is just not very popular with Kentucky voters right now, and he is viewed unfavorably by at least half of the voters.
