If the House has the courage to not raise the debt ceiling, the Senate and the White House will be forced to craft a budget that fits within the current budget ceiling. That will force REAL SUBSTANTIVE BUDGET CUTS, as neither side will have a choice.
There is nothing the Senate or the White House can do about it, if House Republicans have the courage to do it.
That is the change that people voted for in 2010. Not the typical “politics as usual” and watered down garbage that is exemplified by the current GOP budget.
