The latest Siena poll shows Hoffman opening up a lead in a very tight race, with the majority of Scozzafava voters breaking neither for Owens nor Hoffman:

Republican Assembly member Dede Scozzafava still gets six percent support, but since her decision to suspend her campaign and support Owens, the number of undecided voters has doubled from nine percent to 18 percent, according to a new Siena (College) Research Institute poll of likely voters.

One interesting stat: Joe Biden's favorability rating is at a paltry 41 percent.

“Hoffman’s favorability rating shot up from a net positive four points to a now net positive 14 points – 47-33 percent,” [Siena pollster Steven] Greenberg said. “Owens’ favorability dropped slightly from a net positive four points to a net negative one point.

“Vice President Joe Biden comes to the 23rd CD today with a 41-37 percent favorability rating, although he is strong, 64-18 percent, with Democrats,” Greenberg said.

The poll of about 600 likely voters was conducted yesterday November 1; it has a margin of error of +/- 4 points.
