Ohio Gov. John Kasich (R) gets an overall positive nod from registered voters for the first time since his 2011 inauguration, according to a new Quinnipiac poll.

Forty-two percent of registered voters approve of the job he's doing, while 35 percent don't. His favorability is also above water, 40 percent to 34 percent.

But more voters say that he doesn't deserve reelection than think he does, by a 43 to 36 percent margin. Almost as many Republicans (41 percent) are open to a Kasich primary challenger as are not (45 percent).
