61% of adults from New York’s 13th Congressional District say their U.S. Representative, Republican Vito Fossella, should remain in office, according to an exclusive SurveyUSA poll conducted for WABC-TV in New York. 32% say Fossella should resign.

Both Republicans and Democrats say Fossella should stay put: 66% of Republicans and 55% of Democrats say he should remain in office.

Fossella has been in the news following a drunk-driving arrest in Virginia and for acknowledging having fathered a child during an extramarital affair. SurveyUSA did not ask specifically about the recent coverage of Fossella, but simply asked his constituents questions about his job performance and his political future.

Other findings:

Fossella has a high approval rating among his constituents — 67% approve of his job performance, 28% disapprove, yielding a Net Job Approval of Plus 39. By way of comparison, statewide SurveyUSA research conducted in April shows New York Governor David Paterson has a Plus 27 Net Job Approval; Senators Hillary Clinton and Chuck Schumer have approval ratings of Plus 17 and Plus 29, respectively. Fossella has a positive approval rating among Republicans and Democrats alike.

Asked if Fossella should run for re-election in the fall, however, numbers shift somewhat: overall, 53% say he should seek re-election; 42% say he should not. Republicans say he should run by a margin of nearly 2-1; Democrats are divided equally on the question. Fully crosstabbed results of the poll are here.

Two weeks to the Democratic Primary for President in Kentucky, Hillary Clinton remains decisively atop Barack Obama, according to this fourth tracking poll conducted by SurveyUSA for WHAS-TV in Louisville and WCPO-TV in Cincinnati. Today, it’s Clinton 62%, Obama 28%, effectively unchanged from SurveyUSA polls released on 04/29/08 and 04/15/08. Clinton leads in every region of the state and in every demographic subpopulation of consequence.

Kentucky votes, along with Oregon, on May 20.

Here’s the take from the political reporter at WHAS, Mark Hebert.

On the eve of the North Carolina Democratic Primary, with 25% of votes already cast, Barack Obama has no breathing room in his hope to defeat Hillary Clinton in popular votes, according to SurveyUSA’s 8th and final tracking poll, conducted exclusively for WTVD-TV, the ABC-owned TV station in Raleigh. On the final day of the fiercely fought campaign, it’s Obama 50%, Clinton 45%. There is no foreseeable outcome in North Carolina, regardless of which candidate wins the popular vote, where one candidate collects significantly more Convention delegates than the other. Therefore, the exact final vote totals have much more symbolic importance than real importance. The popular vote is remarkably stable: In 6 SurveyUSA polls released since Super Tuesday, Obama has polled at 50%, 49%, 49%, 50%, 49%, 50%. The contest is stable among men, where Obama leads by 11. The contest is stable among women, where the two remain tied. In Charlotte and Western NC, there is the slightest momentum for Clinton. In the Research Triangle, in Southern NC and in Coastal NC, there is slight offsetting momentum to Obama. The net is a wash. If Obama wins, it will be entirely from the 19% of voters who describe themselves as Liberal. Clinton leads by 9 among Conservatives and leads by 8 among Moderates. If Obama wins the popular vote, it will be because of his 16-point advantage among Liberals. Clinton has increasing momentum among voters age 50 to 64, where she has gone from 30% in January to 51% today, her highest showing. Among those age 65+, Clinton leads by 20 points; the more seniors who vote, the better Clinton does. But there is offsetting momentum among younger voters, some of whom may be first-time voters, and not all of whom may show-up at the precinct. 1 in 4 of SurveyUSA’s likely voters say they have already voted. Among those who say they have already voted, Obama leads by 16 points. Among those who say they will vote on Primary Day, Obama and Clinton are effectively tied.
