Presidential Candidate: Senator John Kerry of Massachusetts.
Who might have given John Kerry the edge to be competitive in 2004, to have not been shut out of the prototypical blue states? Or even have seriously challenged George Bush for the Presidency?
The vast majority of these people will be those who ran for President themselves, considered running, or declined to run after being asked, with maybe one or two ideas of who might have been a good or interesting option (Some of which are probably a little out there).
And apparently I'm making this a series.
