WASHINGTON--Is there room in the Republican Party for genuine moderates? Truth to tell, the GOP can't decide. More precisely, it's deeply divided over whether it should allow any divisions in the party at all. That's why the brawl in a single congressional district in far upstate New York is drawing the eyes of the nation. Conservatives are determined to use the race to prove that there is no place in the party for heretics, dissidents or independents. President Obama set up the fight by nominating the district's former representative, John McHugh, as his Army secretary.
