As the left continues to lecture conservatives about their political future -- because, after all, Dems have been fully in charge for more than 100 days now -- let's recount a couple of facts: The Iraq war was supported by more than 60 percent of Americans. Polls showed wide-ranging support for the Patriot Act. Jimmy Carter was once president.

What's beloved today may be reviled tomorrow. Americans are a fickle bunch.

It's possible that voters who opposed a "stimulus" plan that only stimulated the colossal growth of government will not be the extremists tomorrow. It's possible that citizens who protest against the nationalization of the auto and banking industries will be proved right one day. Who knows? Those nutty protestors with their crazy opposition to the socialization of health care and energy policy may look prescient someday.

Granted, principles won't win you elections. (Just ask Specter.) You need big tents -- and cliches about big tents. But if you don't have cause or purpose, what's the point of winning anyway?
