A recent scandal regarding campaign contributions has damaged New York City voters' opinion of Liu, long considered a likely mayoral candidate. Federal investigators have been investigating Liu's campaign fundraising apparatus, leading to a high-profile arrest last month of a prominent Liu fund-raiser. Liu's job-approval rating has crashed from its meteoric highs earlier this year. Now, just 38 percent of Big Apple voters approve of the job he is doing, while 35 percent disapprove. In mid-October, 50 percent approved of Liu's job performance, and only 23 percent disapproved. Forty-six percent of voters say Liu would not make a good mayor, while only a quarter of voters think we would make a good mayor. "Liu has been in the news a lot, in a bad way," said Mickey Carroll, director of the Quinnipiac University Polling Institute. "All those negative stories about his fundraising have zapped his job-approval numbers." The Quinnipiac poll was conducted Dec. 7-12, surveying 1,242 registered voters in New York City. The margin of error is +/- 2.8 percent.
