A recent formula for determining the electability of Presidential and vice-presidential candidates uses things like the number of years they've served as President, Vice-President, House Representative and Governor (being a Senator apparently counts for nothing) and advantageous backgrounds (son of a Senator, general, that sort of thing). It's been tweaked to successfully predict the outcome of all previous Presidential elections, ever, and now purports to predict the next election.
Having been Governor of Vermont for so long, Dean ends up ahead of the field, and is electable by himself irrespective of who he chooses as Vice-President. Others are not so fortunate:
Joseph I. Lieberman would need to choose someone who has been a governor and/or U.S. Representative for at least five years, who is the child of a U.S. Senator, who has been a banker, and who has been a college or university president or chancellor. The existence of such a person is left as an exercise for the Lieberman campaign.
