Ras: Corbett up 10; Senate race tossup

A new poll from Rasmussen shows the Pennsylvania governor's race to be the closest it's been so far, but Tom Corbett still leads Dan Onorato 49-39. A month ago, he was up 49-33.

A few other nuggets from their survey of likely voters in the Keystone State shows that 54 percent favor a repeal of the new health care reform bill and 57 percent would like an Arizona-style immigration law in the state. President Barack Obama has a 47 percent approval rating in PA.

The polling service also rates the Pat Toomey-Joe Sestak Senate race as one of 10 "tossups" around the country, though it doesn't put out any new numbers.

Though considered a right-leaning organization, Rasmussen scored pretty well in Nate Silver's analysis of accurate polls last month.
