Joe Klein of Time Magazine says Al Gore may be the answer to the Democratic Party's problems. He says that both Barack Obama and Hillary Clinton may be too damaged by their infighting to win the general election, so they could agree to the compromise candidacy of Al Gore. Obama may then become Gore's running mate.
This is a horrible idea, and not because of Al Gore himself. Nominating someone who has not even been in the running in the primaries would be far less democratic than nominating a candidate who is a close second in popular votes and pledged delegates. Also, I don't see why either camp should agree to this. Obama would rather be the presidential nominee, not the VP candidate, while Hillary Clinton has no reason to agree to a ticket which includes Obama, unless it includes her as well.
I must say I'd be much happier to vote for Al Gore than for Obama, but it would be morally (and possibly politically) wrong for the Democratic Party to nominate anybody other than the two candidates left standing.
