Governor Jon Corzine has a 49%-32% approval rating — his highest since taking office almost one year ago — according to a new Quinnipiac University poll released today. That’s considerably better than James E. McGreevey’s upside-down 37%-42% in December 2002, but not even close to Richard Codey’s 68%-16% numbers after his first year as Governor. While Corzine appears to be well liked by New Jerseyans (including 28% of Republicans), his base vote does not seem to want him to run for President — at least not in 2008. Nearly three out of every four voters (74%) say Corzine should not run, while just 12% believe he should. More than half (53%) of the New Jersey voters polled say the former Goldman Sachs Chairman and U.S. Senator is not qualified to be President, and only 26% say they would vote for him if he ran; 61% say they would not.
