New Mexico’s U.S. Senate race, which pits former Republican congresswoman Heather Wilson against current Democratic congressman Martin Heinrich saw more outside money flow in from environmental groups opposing Wilson.

The nonprofit Sierra Club Political Committee reported spending $140,000 on salaries, benefits, consulting and media buys against Wilson, according to documents filed with the Federal Election Commission Thursday.

On July 17, the Sierra Club began airing the anti-Wilson ad, “Dirty Water, Dirty Politics,” featuring a school child drinking from a water fountain gushing brown water.

And Environment America Inc., also a nonprofit, reported spending about $13,000 canvassing and strategizing on behalf of Heinrich between July 11 and July 19, the group reported.

The race, to replace retiring Democratic Sen. Jeff Bingaman, is as an important test for Republicans since the state has a large Hispanic population and those voters tend to lean left. A win for Republicans in New Mexico could help the GOP take the Senate.

The League of Conservation Voters has aired three TV ads against Wilson since June 21: “We’re All Paying for It,” “Emma” and “Who’s Wilson With?

The U.S. Chamber of Commerce and conservative super PACs American Commitment and American Crossroads have aided Wilson’s run with “Another,” “Stands,” and “Fighting for New Mexico.”

The Sierra Club Political Committee, Environment America Inc., and the U.S. Chamber of Commerce can accept unlimited donations from individuals, corporations but are not required to reveal their donors.
