Via this comes this MSNBC clip of a Bubba sighting:

Andrea Mitchell: [Bill Clinton] headlined a party last night for Ben Cardin... and he ridiculed what Republicans have been saying about Democrats...

Bill Clinton: ...you have to vote for us because our opponents are no good... and because they'll tax you into the poor house... and on the way to the poor house you'll meet a terrorist on every street corner... and when you try to run away from the terrorist you'll trip over an illegal immigrant... isn't that their thing? That's what they're saying...

Yes, but only some of them are truly concerned about the vital issues of terrorism and illegal immigration. Some, like Bush, Clinton, and the Dems are more concerned with other issues.

Clinton made this same joke at a recent ASU appearance.
