There's not much movement in the Republican Senate primary in the Bluegrass State, where Rand Paul is maintaining a 15-pt. lead over establishment choice Trey Grayson. That comes despite fundraising having trailed off significantly for Paul (maybe his supporters dug up all the bullion they could find hidden in their yards), but he seems to have already locked in enough TV advertising to keep his substantial edge over the next month.
The real movement is on the Democratic side, where AG Jack Conway, usually down double-digits to Lt. Gov. Dan Mongiardo, is suddenly within 3. (Maybe the attacks on Mongiardo's first-class business travel hit their mark?) Weirdly, though, the crosstabs seem very odd: while Conway is perceived as more liberal than the pro-life Mongiardo, Conway leads among self-described conservative and pro-life Democrats while Dr. Dan is up among liberal and pro-choice Democrats. Two possible explanations from the digest's comments thread, both of which are very plausible, are that Mongiardo still has a lot of goodwill among liberals for almost taking down Jim Bunning in 2004, while Conway's day job as AG may win over lots of law-and-order types.
