Can congressional Republicans repeal Obamacare?

Washington (CNN) -- While conservatives are still seething over last week's Supreme Court ruling saving President Barack Obama's health care overhaul, top Capitol Hill Republicans are gleefully using the decision to fire up their base with promises of a repeal in 2013.
The high court's 5-4 decision "underscores the urgency of repealing this harmful law in its entirety," House Speaker John Boehner, R-Ohio, said shortly after last Thursday's ruling. "Republicans stand ready to work with a president who will listen to the American people."
Roberts ruled that the controversial individual mandate -- the core part of the law forcing Americans to pay a fine if they don't have health insurance -- is actually a tax. And a complex congressional rule known as reconciliation would allow Republicans to change certain tax and spending components of the health care law with only a bare Senate majority.
"The chief justice said (the mandate) is a tax, and taxes are clearly what we call reconcilable," Senate Minority Leader Mitch McConnell, R-Kentucky, said on Fox News Sunday. "That's the kind of measure that can be pursued with 51 votes in the Senate. And if I'm the leader of the majority next year, I commit to the American people that the repeal of 'Obamacare' will be job one."
The reconciliation process could also be used to strip funding for the statute, one senior GOP strategist told CNN.
