Republicans on Capitol Hill are talking about each other as if they belonged to opposing parties. It’s all about trying to stop Obamacare. Tea partiers, backed by well-funded conservative groups, say they’re willing to shut down the government or stop the US from paying its bills.

Washington veterans say nothing quite like this has ever happened before. We look at what’s at stake for both sides and for the nation.
