"Wait a minute, you can't say one thing back then and now say something complete opposite now," Obama exclaimed as the crowd roared in laughter.
After getting through the list, Obama wrapped up by concluding, "Those kinds of tricks, that kind of approach to politics is what has to stop. Nobody believes anything. Voters don't believe what politicians are saying."
He then promised the audience, "You won't hear me saying one thing one day to one audience and then saying something else another day to a different audience because I think it's politically convenient."
