"Martin Heinrich told New Mexico he would fight unemployment, but he spent a trillion of our tax dollars on a stimulus for failed companies here and jobs overseas."

That's part of the text in an ad against Heinrich, the 1st District Congressional Democrat running for US Senate. The fact-checking website Politifact.com gave the ad a false rating, writing that it's "flat wrong to suggest that any large percentage of stimulus spending ended up going to failed companies and jobs overseas."

"About four-fifths of the total spent was allocated to items that literally couldn't go for those purposes," Polifact continues. "We rate the claim false."

The ad was paid for by American Future Fund, an Iowa-based "social welfare" 501(c)(4) that clocked in $23 million in revenue in 2010. The conservative organization is one of the many dark money groups now free to spend unlimited amounts of cash on independent expenditures.

Heinrich was one of every House Democrat who cast a vote for the stimulus, which ended up costing $814 billion. Every House Republican--save one who abstained--voted against it.

Actually the stimulus helped create thousands of jobs right here in New Mexico. According to the New Mexico Office of Recovery and Reinvestment, at least 21,000 people in the state can thank stimulus dollars for full or part-time jobs since February of 2009, when the stimulus was enacted, through March of 2011. And those are only the jobs created through state agencies.
