Meanwhile, down in Kentucky, things are looking surprisingly good for GOP gubernatorial nominee Matt Bevin and surprisingly ominous for the Democrats, who hope to keep control of the governor’s mansion. Stu Rothenberg concludes:

The bulk of the campaign is still to come, but we are changing The Rothenberg & Gonzales Political Report/Roll Call rating of the race from Tossup/Tilts Democratic to pure Tossup. And if Democratic attacks don’t start to stick to Bevin, the race could start to look even better for the GOP.

Yesterday the RGA unveiled a new ad hitting the Democratic nominee, state attorney general Jack Conway.

Democrats contend attacking Conway on Obamacare won’t work, because the state’s health exchange is more popular and successful than in most other states. A May 2014 poll found Kentuckians feel a lot worse about “Obamacare” than the state exchange, named “Kynect.” At the time, liberals chuckled that opposition to Obamacare was mostly a matter of semantics; they suggested poll respondents fixated on the “Obama” part of the name and reflexively opposed a program they otherwise supported. But a more recent poll from January 2015 suggests Kentuckians still aren’t that warm on the giant health reform; a poll of adults — not registered voters, not likely voters — put “the Affordable Care Act” at 39 percent favorable views and 41 percent unfavorable views. Only 18 percent told the survey the law had helped them; 21 percent said the law had hurt them.
