Republican State Attorney General Tom Corbett holds a 10-point lead again this month over Democrat Dan Onorato in Pennsylvania’s race for governor.

The latest Rasmussen Reports telephone survey of Likely Voters in Pennsylvania shows Corbett picking up 48% of the vote. Onorato, the chief executive of Allegheny County, earns 38% support. Five percent (5%) prefer some other candidate in the race, and 10% remain undecided.

Last month, Corbett posted a near-identical 49% to 39% lead.  It was the closest the contest had been to date.

In May, just after both candidates won their party primaries, Corbett was ahead 49% to 36%.  In surveys since February, the Republican's support has ranged from 45% to 52%, while the Democrat's in the same period has grown from 26% to 39%.

Corbett holds modest leads among both male and female voters.

Eighty-four percent (84%) of Republicans and 21% of Democrats support Corbett. Onorato picks up just 62% of the votes from his own party. Among voters not affiliated with either major party, the Republican holds a two-to-one lead.

This statewide telephone survey of 750 Likely Voters in Pennsylvania was conducted on July 14, 2010 by Rasmussen Reports. The margin of sampling error is +/-4 percentage points with a 95% level of confidence. Field work for all Rasmussen Reports surveys is conducted by Pulse Opinion Research, LLC. See methodology.

Pennsylvania like many states is facing serious budget problems, driven in party by shortfalls in tax revenue caused by the bad economy. Just eight percent (8%) of Pennsylvania voters now rate the economy as good or excellent. Nearly half (49%) describe the economy as poor.

Twenty-six percent (26%) say the economy is getting better, but 46% think it is getting worse. Sixty-four percent (64%) say the country is in a recession.

Sixty-one percent (61%) of voters in the state favor passage of an immigration law like Arizona’s in Pennsylvania, identical to voter views nationwide.  Twenty-eight percent (28%) oppose such a law in the state.

Sixty-two percent (62%) of the larger group that favors such a law supports Corbett. A similar number (63%) of those who are opposed to an Arizona-like law in their state favor Onorato.

Corbett is viewed Very Favorably by 21% of Pennsylvania voters and Very Unfavorably by nine percent (9%).

Seventeen percent (17%) have a Very Favorable opinion of Onorato, while 13% regard him Very Unfavorably.

Roughly one-in-five voters don’t know enough abut either man to express any kind of opinion of them. That’s one reason why at this point in a campaign, Rasmussen Reports considers the number of people with a strong opinion more significant than the total favorable/unfavorable numbers.

Forty-two percent (42%) approve of how current Democratic Governor Ed Rendell is doing his job. Fifty-seven percent (57%) disapprove. This is little changed in recent months.

Rasmussen Reports also has released recent polls on the 2010 governor's races in Alabama, Arizona, California, Colorado, Connecticut, Florida, Georgia, Hawaii, Idaho, Illinois, Iowa, Kansas, Massachusetts, Maryland, Michigan, Minnesota, Nebraska, Nevada, New Hampshire, New Mexico, New York, Ohio, Oklahoma, Oregon, Rhode Island, South Carolina, South Dakota, Tennessee, Texas, Vermont, Wisconsin and Wyoming.
