Why is the Tea Party winning? Wall Street and big business hold the purse strings in the GOP, but the Tea Partiers are now the ground troops. House Republicans need those ground troops to get out the vote in 2012. And they figure Wall Street and big business will stake them regardless of what happens.
But Boehner and his colleagues are playing with fire. If the debt ceiling isn't raised and the financial system begins to collapse, the GOP loses not only Wall Street and big business. It loses everyone who's still sane.
