Nobody gets it better than Bill Clinton gets it:
“In Tampa the Republican argument against the president's re-election was pretty simple: We left him a total mess, he hasn't finished cleaning it up yet, so fire him and put us back in," Clinton will say. “I like the argument for President Obama's re-election a lot better. He inherited a deeply damaged economy, put a floor under the crash, began the long hard road to recovery, and laid the foundation for a more modern, more well-balanced economy that will produce millions of good new jobs, vibrant new businesses, and lots of new wealth for the innovators."
“The most important question is," Clinton will say, "what kind of country do you want to live in? If you want a you're-on-your-own, winner-take-all society, you should support the Republican ticket. If you want a country of shared prosperity and shared responsibility -- a we're-all-in-this-together society -- you should vote for Barack Obama and Joe Biden.”
