Before the health care fight, before the economic stimulus package, before President Obama even took office, Senator Mitch McConnell, the Republican minority leader, had a strategy for his party: use his extensive knowledge of Senate procedure to slow things down, take advantage of the difficulties Democrats would have in governing and deny Democrats any Republican support on big legislation.
Republicans embraced it. Democrats denounced it as rank obstructionism. Either way, it has led the two parties, as much as any other factor, to where they are right now. Republicans are monolithically against the health care legislation, leaving the president and his party executing parliamentary back flips to get it passed, conservatives revived, liberals wondering what happened.
