DeMint later said the president was "steamrolling the American people," saying he thinks Americans feel like Obama hasn't been listening to them.
Joining DeMint in the debate was Sen. Robert Menendez, D- N.J., the man in charge of holding on to a democratic majority in the Senate, who said the "biggest takeaway from Massachusetts is that there is enormous economic angst in the country."
The chair of Democratic Senatorial Campaign Committee insisted that the DSCC "did everything we could in resources, in personnel to help Martha Coakley win that election" in Massachusetts.
This week, in a 5-4 decision the Supreme Court ruled the government may not ban political spending by corporations in elections.
DeMint lauded the decision, saying "we can't promote freedom and democracy by repressing free speech." But he did allow for the possibility that restrictions might be needed on political donations on foreign corporations.
"Right now, foreigners cannot give to the political process. And I hope, as this thing is sorted out, that we'll make sure that this is an American focus," DeMint said.
"The problem is, a corporation is a corporation is a corporation," Menendez said. "And a foreign corporation is going to be able to spend their monies in determining who is elected to the United States Congress. That's not good for the average citizen."
Menendez, who vociferously opposed the Supreme Court ruling, said that the justices' decision would "put enormous amounts of money and influence on behalf of big oil, health insurance companies, big banks" into the political system.
