Mr. Cuomo’s popularity appears to be fueled in part by widespread doubts about Mr. Paladino’s temperament and qualifications.

Some 59 percent of voters in the poll said that Mr. Paladino did not have the right temperament and personality to be a good governor, while 55 percent said that Mr. Paladino, a novice candidate who made millions as a real estate developer, did not have the right kind of experience.

Only 11 percent of voters in the poll had a favorable view of Mr. Paladino.

And when asked what comes to mind when they hear his name, voters who were surveyed offered a collection of negative personality traits, like “angry,” “bigoted” or “obnoxious.”
