It will probably be Joe Biden.
When you get right down to it who do you want as your president
McCain (with lots of foreign policy experience, and will make decisions,if he is elected president) or;
Obama (with a vice president with lots of foreign policy experience, but ultimately Obama will have to make the final call if he is elected president.)
Personally I want McCain for president, somebody who has the experience to make tough decisions, not somebody who has the ear of a foreign policy expert.
One quick final note: They use to say the same thing about George Bush;
"oooooh, he's not smart, but he has smart people around him and that's all you need to be president!"
ah, no you have to be smart and experienced to be president, look at the presidency of a one term governor from Texas. You think that's bad, wait and see what a first term Senator form Illinois will be like as President. G-d forbid.
It will be the second coming of Jimmy Carter.
