If Siena’s final pre-general election poll is on the money, it could be a very long and tense election night.

The survey continues to show Democratic frontrunner Andrew Cuomo with a comfortable double-digit lead over his GOP challenger, Carl Paladino, (58-33). Paladino now leads the AG among Republicans, 62-27, and made inroads with independents, too, although Cuomo is still ahead there, 48-40.

Ditto for Sen. Kirsten Gillibrand in her race against former GOP Rep. Joe DioGuardi (57-37) and extra ditto for Sen. Chuck Schumer vs. Republican Jay Townsend (64-32).

But the other two statewide races are deadlocked.

The real surprise is the state comptroller’s race, in which Republican Harry Wilson has closed a 17-point gap between himself and Democratic incumbent Tom DiNapoli. The two candidates are tied at 44 percent with 12 percent still undecided and only two days (counting this one) remaining in the campaign.

Wilson is now ahead in both the suburbs (nine points) and upstate (16 points) – both areas where DiNapoli previously had a slim lead.

The first time candidate and former hedge fund manager also managed to, as Siena spokesman Steve Greenberg put it, “bring home” Republicans, and is now leading among his fellow GOPs by 62 points, up from 36.

Wilson still remains unknown to some 60 percent of the voters (it’s 37 percent for DiNapoli). He just recently dumped another $1.1 million into his campaign to fund a last-minute TV blitz, but will it be enough to push him over the line to victory?

Also, Greenberg noted, nearly one-quarter of Cuomo voters and nearly one-quarter of voters unfavorable to the Tea Party are supporting Wilson. He’s doing better with those two categories of voters than any other Republican on the statewide ballot.

Democratic Sen. Eric Schneiderman and Republican State Island DA Dan Donovan are also tied at 44 percent, which means Donovan managed to close the seven-point gap between himself and his opponent since the last Siena poll.

Donovan made up most of that ground by gaining the support of independents. He’s also far ahead (21 points) in the downstate suburbs, but the senator trimmed the DA’s upstate lead from 12 points to 9.

“Voters have a clear choice between two candidates whose campaigns have certainly highlighted their philosophical differences and approaches to the Attorney General’s office,” said Greenberg.

“Neither one has persuaded a majority of voters to support them, and with 12 percent undecided heading into the final days of the campaign, this race looks like the proverbial coin toss.”
