It's Tom Corbett's race to lose for Pennsylvania governor.

From Rasmussen Reports:

The latest Rasmussen Reports telephone survey of Likely Voters in Pennsylvania shows that Republican State Attorney General Tom Corbett attracts support from 49% of Keystone State voters in his bid to become governor. His Democratic challenger, Allegheny County Chief Executive Dan Onorato, earns 33% of the vote.

Five percent (5%) say they'd prefer some other candidate, and 13% are undecided.

These results are little changed since mid-May when both candidates won their party nomination. In fact, every poll of the race has shown Corbett ahead with support from somewhere around half the state's voters.
