WASHINGTON — The campaigns of Rep. Heather Wilson, Albuquerque Republican, and her Democratic challenger, Attorney General Patricia Madrid, have spent more than $2 million to win your vote on Nov. 7, but political parties' special interest groups are pouring even more money into the 1st Congressional District Race.

The latest intervention is by a group with ties to former House Minority Leader Tom DeLay and the Swift Boat group of veterans who attacked the war record of Sen. John Kerry, Massachusetts Democrat, in the 2004 presidential campaign.

Reports filed last week with the Federal Election Commission show that Americans for Honesty on Issues has spent $165,000 on a television ad accusing Madrid of wanting "your taxes super-sized."

The group received $2 million from Houston developer Bob Perry, who also funded the Swift Boat group. The group is led by Sue Walden, a Houston political consultant with close ties to DeLay according to the New York Times.

The independent expenditures - so called because they are not supposed to be coordinated with the campaigns - show how much the Wilson-Madrid race is viewed nationally as a crucial battle for control of the House of Representatives.

In the last month alone, the Democratic Congressional Campaign Committee and the National Republican Congressional Committee have spent more than $1 million on the Wilson-Madrid race, mostly for advertising, with some GOP money paying for phone banks.

Alex Burgos, spokesman for the National Republican Congressional Committee, said it doesn't spend money on phone banks in every district but it is in Wilson's case.

"We are committed to holding onto the seat and are investing the resources necessary to do the same," Burgos said.

Kate Beddingfield, a spokeswoman for the Democratic Congressional Campaign Committee, said it doesn't comment on its media strategy or spending.

Special interest groups also have joined the fray.

The National Association of Realtors political action committee has spent $761,000 in the last month on television ads supporting Wilson.

Mary Trupo, spokeswoman for the committee, said the Wilson race is one of about five campaigns where they have made independent expenditures.

"She was a very easy one for us," Trupo said, because of her support for the real estate industry, especially for legislation that would let associations like the Realtors offer small a small business health plan for their members.

The National Education Association PAC has spent $101,000 against Wilson and $58,000 in support of Madrid. The League of Conservation Voters reported $81,000 in expenditures for Madrid and $2,200 against Wilson.

Emily's List, which supports Democratic candidates, spent $148,000 to support Madrid.

Emily's List is targeting campaigns in about 15 states where pro-choice Democratic women are running, said Karen White, national political director for the group. The group's Web site features a photo of Madrid and asks for contributions.

"The people in this district deserve a change," White said. "Heather Wilson I would not consider a moderate at all. She has been in lockstep with the Bush administration."

The group is using paid mail to target "dropout women," those voters who only go to the polls for a presidential election, White said.

And the American Federation of State, County and Municipal Employees filed notice that it intends to spend $48,000 in support of Madrid.

As for the campaigns themselves, reports filed Sunday with the FEC show that Wilson entered the last five weeks of the campaign starting Oct. 1 with a better than two-to-one advantage in funds: $1.3 million to $539,000.

Wilson also raised more money in July, August and September - a little more than $1 million to $687,000.

For the entire campaign, Wilson has raised about $3.8 million and spent more than $2.8 million. Madrid has raised more than $2.5 million and spent about $2 million.
