(CNN) – The conservative Club for Growth is taking aim at both the Democratic and Republican candidates running in the special election to fill former New York Rep. John McHugh's seat.
The group, which has already backed third-party candidate Doug Hoffman, is spending $250,000 on radio and TV ads targeting Democrat Bill Owens and Republican Dede Scozzafava.
Hoffman registered 16 percent in the Siena poll released Thursday. Scozzafava draws 35 percent in the same survey, and the well-funded Owens takes 28 percent.
"Who's more liberal: Dede Scozzafava or Bill Owens?" asks the narrator in the 30-second TV spot. "Four of a Kind," which ties Scozzafava to New York's unpopular Democratic governor, David Paterson, and Owens to House Speaker Nancy Pelosi.
Pelosi and Paterson pulled approval ratings of just 33 percent and 31 percent in New York's 23rd congressional district in the Siena poll released a month before voters head to the polls to pick the replacement for McHugh, President Obama's new Secretary of the Army.
That survey found that Scozzafava has the support of nearly half the Republicans polled, while just over 1 in 5 back Hoffman.
