A brand new Monday morning poll from Siena for New York Times Upshot shows Republican incumbent Claudia Tenney with a one-point lead (46-45 percent) over her Democratic opponent, Anthony Brindisi, just hours before the polls open on Tuesday.

"This is extremely close," said Steve Greenberg, spokesperson for the Siena poll. "If there's ever been a perfect example of 'every vote counts' the race in NY-22 is it."

The poll also showed that nine percent of likely voters in the 22nd congressional district are still undecided. That's the same number of undecided voters polled in two previous surveys done in August and October. "Most of this undecideds are Republicans who are struggling because they favor Trump but don't particularly like Tenney," said Greenberg.

The Siena poll made 17,444 calls and spoke with just 506 people in the district and comes with plus or minus margin of error of five percent.
