(CNN) - If you need more evidence that national Democrats may be nervous about holding a House seat in the ninth congressional district of New York that was long held by former Rep. Anthony Weiner, well here it is: House Majority PAC announced Friday they would start running television ads in the district that criticize the Republican candidate in Tuesday's special election for embracing the tea party movement.
On Monday, Sept. 12th, CNN will broadcast the "Tea Party Republican Debate," live from Tampa, Florida at 8 p.m. ET. Follow all the issues and campaign news leading up to the debate on CNNPolitics.com and @cnnpolitics on Twitter.
The independent group, which is committed to helping the Democrats try and recapture the House of Representatives next year, confirms to CNN that they will spend six figures on their ad buy and that the commercial will run on cable and broadcast in the expensive New York City media market starting Friday through Election Day. They say the ad won't run on Sunday, which is the tenth anniversary of the 9/11 terrorist attacks.
The move by House Majority PAC comes one day after the Democratic Congressional Campaign Committee announced a half million dollar ad buy in the race.
In the commercial, a man dressed as a Founding Father says that the Republican candidate in the race, Robert Turner, "seeks election to Congress praising tea party logic. But 'tis no tea party of mine."
The ad also highlights the New York Times endorsement of Democratic candidate David Weprin.
"If Republicans are going to play footsies with the tea party, the House Majority PAC is going to stomp on their toes," said Ali Lapp, Executive Director, House Majority PAC, in an email release Friday morning.
Turner is a former cable tv executive and Weprin is a state assemblyman. The winner of Tuesday's contest will fill the remaining 14 months left in Weiner's term. Weiner resigned in June after his Twitter account showed lewd photos of the congressman.
Even though Democrats greatly outnumber Republicans in the district, which covers parts of the boroughs of Brooklyn and Queens, recent polls suggest the race is close.
A Siena College Research Institute poll from early August indicated Weprin led Turner by a narrow six-point margin. A new poll in the race is expected to be released later Friday morning.
In another sign that Democrats are concerned about keeping the seat in party hands, Jeremy Bird, national field director for Obama for America, released an email this week to supporters asking for ground troops to help with get out the vote efforts in the district.
