He hasn't declared yet, but that hasn't stopped Project Vote-Smart from putting up some useful information on the Senator, including links to transcripts of interviews (including the Sputtery and Colmes interview I mentioned earlier,) biographical info, and eventually position statements.

Also, Salon has an article today about the Senator's proposal last fall for a reasonable resolution of the situation in Iraq.  It was ignored by the Democrats, leading to the mess they find themselves in today.  I think it provides a good view of his position on the war.

Lastly, don't forget that tonight is National Gary Hart Meetup Day.  If you're interested in talking with other Hart supporters and especially if you are interested in volunteering, be sure to check out your local Meetup.
