President Barack Obama said again Monday, he won't negotiate with Republicans in order to raise the debt ceiling.

"If the Republicans in Congress have made a decision that they want to shut down the government in order to get their way, then they have the votes, at least in the House of Representatives, probably to do that," Obama said.

Avlon: Call it the default ceiling

The problem is - Republicans say they are in fact probably going to do that.
