Can Indiana go blue?

At Salon, Walter Shapiro looks at the possibilities.

That said, this guy from the convention in Denver should NOT be voting Obama:

By my reckoning, I saw four different Obama ads in two days, with the most frequently aired commercial featuring Indiana's Barney Smith, a laid-off RCA worker from Fairmont, repeating the same catchphrase that he used in his speech to the Democratic convention, “It’s time for a president who puts Barney Smith before Smith Barney.”

Given that Obama voted for Smith Barney three weeks ago, Barney Smith should be voting Green, Socialist or whatever progressive options he has.
