Poll: 18% undecided in NY-23

From NBC's Mark Murray
Now that the NY-23 special congressional election has essentially turned into a two-person race, a new Siena Research poll has Conservative Doug Hoffman leading Democrat Bill Owens by five percentage points, 41%-36%, with Republican Dede Scozzafava (who withdrew from the race on Saturday) now getting just 6%.

But this might be the most interesting number: 18% are undecided -- a very large number with just a day before the election.

"With nearly one in five voters undecided the day before Election Day and voters still trying to comprehend the dramatic withdrawal of Scozzafava, and her subsequent endorsement of Owens, this is still a wide open race," Siena's Steve Greenberg said. "The two candidates and campaigns are both in a sprint to try and convince these undecided voters to support them. Which ever campaign succeeds in convincing the undecided voters and then getting them to the polls tomorrow, will likely be looking at a victory tomorrow night."

The poll was taken of 606 likely voters in congressional district, and it has a margin of error of +/- 4%.
