Franklin and Marshall College pollster and political analyst Terry Madonna does not believe that Bob Guzzardi, a self-described Republican independent from Montgomery County, is much of a threat to defeat Tom Corbett in the primary.

“Someone arguing that he’s not a true conservative, that he’s not a true Republican,” says Madonna, “particularly in a primary when Governor Corbett is doing everything he can to win back a significant percentage of Republican voters.”

And while Madonna believes a Guzzardi win is not likely, he says there is the real possibility he could make a strong showing in the primary that would embarrass Corbett.
