Mitch McConnell's seen a significant decline in his standing with Republican voters following his ill fated endorsement of Trey Grayson for the party's Senate nomination, and as a result his home state approval numbers are now by far the worst they've ever been in PPP's Kentucky polling.
PPP's last three polls found McConnell's approval ranging from 44% to 48% to 43%. Now only 34% of voters in the state like the job McConnell's doing with 48% disapproving. And beyond that a near majority of his constituents- 49%- would like to see him lose his role as Republican leader in the Senate to only 38% who think he should continue on in it.
McConnell's seen no change in his standing with Democratic voters since PPP's early May poll of the state. He was at 25/62 then and he's at 24/63 now. With Republicans though he's dropped from a +49 approval spread at 68/19 to now just a +26 at 51/25. He's had a dramatic decline with independents as well from -9 at 36/45 to -33 at 22/55. Kentucky has a relatively small number of independent voters though so those numbers have comparatively little to do with McConnell's overall drop.
Digging deeper into McConnell's numbers his decline in popularity has come completely with conservative voters. His 23% approval rating with moderates is unchanged from two months ago and his 15% standing with liberals is actually slightly improved from 12% in the May poll. But with conservatives, who comprise the largest voting bloc in Kentucky, he's fallen from 67% all the way down to 47%. It's probably a good thing for McConnell that he's not up for reelection again until 2014 because the downward descent in his numbers with the party base suggest he could be the next big target of the Tea Party crowd.
McConnell's learning, like Harry Reid, that it's hard to be a big shot in Washington and maintain your support on the home front.
