Caroline was in charge of picking Obama's VP. She apparently pushed for Biden, so maybe the joke is on Obama?
If Obama wins you can bet there will be a lot of tension in the White House between Obama and Biden.
I saw this quote on youtube and thought it should explain redistribute the wealth to even the most simple minded:
“I taught my daughter a valuable lesson about Obama tonight: I took 3/4 of her Halloween candy and gave some to her neighbor, who didn’t even go out trick or treating.
And I didn’t even tell her that it was from my daughter!
It was spreading her hard-earned, hard-worked-for wealth around.
That’s the same way it will be under a president Barack Obama “
