ELKHART, Ind. (AP) -- Democratic presidential candidate Barack Obama on Wednesday taunted Republican candidate John McCain for agreeing on the importance of keeping tires inflated as an energy-conservation measure after having joined the GOP in mocking the idea.
''It will be interesting to watch this debate between John McCain and John McCain,'' Obama said as he campaigned in Indiana with Sen. Evan Bayh, widely considered a top-tier candidate for running mate.
