The Tea Party is coming after me, Rep. Ed Markey, told supporters in a Thursday fundraising request.

Markey, who is battling Republican Gabriel Gomez for the open U.S. Senate seat in Massachusetts, said he is seeking donations as small as five dollars in an effort to raise $50,000 for his campaign’s “Rapid Response Fund.”

Markey’s email is in reaction to a six-figure ad purchase by a pro-Gomez political action committee. While the PAC does not declare an association with the Tea Party, its treasurer, Nancy Watkins, worked for Rep. Michelle Bachmann, R-Minn., a Tea Party leader.

“They’ve got a ton of money and they are spending it on ads against Ed,” Markey’s email funding request reads. “This is how the right wing thinks it’s going to buy this election for my opponent.”

The PAC is called Americans for Progressive Action. According to a June 6, statement of organization filed with the Federal Election Commission, the group is based in Tampa, Florida.

The Gomez campaign said has not connection with the group and does not know who organized it.
According to Gomez, it’s Markey who is doing the big spending so far.

“He has outspent me four or five to one,” Gomez said, with much of it used to produce negative campaign ads.
