Jon Corzine might need to fight to win a second term as Governor in America's most Democratic state, but today's Quinnipiac University poll offers no indication that he could lose a Democratic primary. Among Democrats, Corzine has a 67%-21% favorable rating, and a 60%-31% job approval rating. (That's not much different from U.S. Senator Frank Lautenberg, who won 60% of the vote against a credible primary challenger; Lautenberg has a 64%-10% favorable rating and a 65%-16% job approval rating among Democratic voter). Democrats, by a 60%-25% margin, say he deserves to win re-election.
Only one New Jersey Governor has lost re-election in a primary: William Cahill in 1973. Brendan Byrne won just 30% of the vote in the 1977 Democratic primary, but that was enough to win in a field of nine candidates. The only New Jersey Governor to lose re-election was Jim Florio, in 1993.
