Only flaw in your twisted logic--Clinton won the big ones, and the Democratic base stuck by her.
Obama, like McCain, can't win it with the independents, but not their base. McCain without the Republican base can't win, and Obama or Clinton without the Democratic base can't win.
Plus, Clinton increased voter turnout yesterday too, just like Obama. But instead of increasing the youth vote, she increased by a sizable margin, two solid blocs that are voting consistently Dem--women and Latinos.
