A new Quinnipiac poll shows that Mayor Bloomberg's approval rating has gone down to 66%, from January's 69%. While it's still a good rating, it is still the lowest rating of his second term (he had a 31% rating in 2003!) and Quinnipiac finds 55% of voters find him "cold and businesslike, not warm and friendly," a finding "consistent among blacks, whites and Hispanics, men and women and in all five boroughs." Quinnipiac's polling director Maurice Carroll explains, "New Yorkers don't warm up to Mayor Mike, but they give him high marks for doing his job." As for an election matchup, Bloomberg still beats both City Comptroller Bill Thompson and Rep. Anthony Weiner. Interestingly enough, Weiner, who signals he may not run for Mayor, has more support than Thompson among voters, but the campaigning really hasn't begun.
