Only 19 percent of the voters questioned in a Siena College Research Institute poll released Monday say Paterson's doing an excellent or good job as governor, and more than four times as many - 78 percent - say he's doing a fair or poor job. Paterson's approval rating is down 7 points from Siena's more recent poll conducted last month.
Eliot Spitzer's former lieutenant governor is up for election in his own right in November of next year.
The poll indicates that if a Democratic primary were held today, Paterson would lose in a hypothetical match up against New York Attorney General Andrew Cuomo by nearly four to one. Cuomo, who has not yet decided on a run for the top spot, is the son of former three-term New York Gov. Mario Cuomo.
If Paterson survives a primary challenge, the poll suggests he would be easily beaten in a general election in a hypothetical matchup against former New York City Mayor Rudy Giuliani.
The new Siena poll's sinking numbers continue a trend seen in a Marist poll earlier this month and a Quinnipiac poll released in February.
Paterson was buffeted by controversy late last year and earlier this year over his decision-making process in picking former Rep. Kirsten Gillibrand as Secretary of State Hillary Clinton's successor in the Senate.
"Both in personal popularity and job performance, David Paterson's standing with voters continues to slide," said Steven Greenberg, Siena New York Poll spokesman. "The speed of his falling numbers is staggering. Two months ago, 60 percent of voters viewed Paterson favorably, and now it's less than half of that. More than two-thirds of voters prefer 'someone else' for governor next year."
The Siena College Research Institute poll was conducted March 16-18, with 626 New York State registered voters questioned by telephone. The survey's sampling error is plus or minus 3.9 percentage points.
