Here’s a question worth pondering no matter what happens tonight: Was there any point to the 2007 stretch of this painfully long campaign? For most of 2007, the polls suggested a Rudy Giuliani versus Hillary Clinton race. John McCain was broke and sinking in the polls. Barack Obama let his historic opportunity pass him by. Even most black voters preferred Hillary for the Democratic nomination. None of this, it is now obvious, turned out to be true. Giuliani didn’t even win a single primary. Hillary is now stumping, however reluctantly, for Obama. Did we really need to go through the first stretch of a campaign that only professionals paid any attention to and didn’t turn out to matter?
