Hate to say it but I think we may wind up with a Lieberman/ McCain ticket.
There is no way that blowhard McCain would ever put himself in a second-fiddle position to whiney milquetoast Lieberman.
McCain knows there is no way he will ever become president as a Republican. He is Libermans best friend. I imagine that Liberman will have to agree to make him a strong VP but being a strong VP is the closest McCain can ever come to being President. He is too old to hope to become President after two terms and besides Hilterbeast would get in the way of that.
I would expect the announcement to come in early 2004 so a year could change things but only health problems will keep McCain from jumping to run with Liberman. Although if the Dems managed to get another seat he might announce sooner.
