President Obama campaigned in Michigan today for his fix to the fiscal crisis -- and slammed Michigan's soon-to-be-enacted right to work law.

Talking about recovery in the auto industry, Obama gave an extended riff against the new law, saying that what "what we shouldn't be doing is trying to take away your rights to bargain for better wages and working conditions. We shouldn’t be doing that."

To loud applause, he added, "These so-called 'right to work' laws, they don't have to do with economics; they have everything to do with politics," he said. "What they're really talking about is giving you the right to work for less money."

He delivered a defense of unions, saying "you only have to look to Michigan -- where workers were instrumental in reviving the auto industry -- to see how unions have helped build not just a stronger middle class but a stronger America...America is not going to compete based on low-skill, low-wage, no workers’ rights. That's not our competitive advantage. There's always going to be some other country that can treat its workers even worse. Right?"
