Fact-checking the U.S. Chamber of Commerce

The U.S. Chamber of Commerce is running ads in a variety of Senate races. This one attacks Virginia's former governor, Democrat Tim Kaine, over his support for President Barack Obama's health care law.

The U.S. Chamber of Commerce jumped into congressional races with a barrage of ads Feb. 8, 2012. They targeted Senate candidates with attack ads, and praised a House Republican for her record, focusing on the economy, jobs and taxes.

But they all had issues with the truth.

Four ads we looked at earned ratings from Half True to False.

The most truthful attack, on a Montana Democrat, took him to task for voting for the 2010 health care law, declaring, "Obamacare (hit) Americans with over $500 billion in new taxes." But that number included more than taxes and ignored substantial federal subsidies for taxpayers, prompting us to rate it Half True.

Two ads earned Mostly False ratings.

The business group said that a Wisconsin Democrat backed raising taxes by $858 billion — a misleading take on her vote against a bill extending Bush-era tax cuts. Meanwhile, in another ad it praised an Illinois Republican in a message warning the nonpartisan Congressional Budget Office said unemployment could top 9 percent in 2013. But that wasn’t the CBO forecast, which ranges from 7.4 to 8.9 percent.

A fourth ad was flatly False.

It saddled a Virginia Senate candidate with support for President Barack Obama’s health care law, saying it "will kill jobs across America." The Chamber of Commerce has failed to prove that it will, and the best projections PolitiFact has, which are based on how the law is actually written, do not suggest that the law will "kill" jobs.
