Let's help get a better sense of what tools political professionals are using, both for advocacy and to help elect candidates: take the 2008 E-Voter Institute Survey of Political and Advocacy Communications Leaders today.

MoveOn announces the winner of its Obama ad contest; Andrew Sullivan, the web, and the fight against obedience, submission, and authoritarianism; a videoblogger asks, where is Ralph Nader's party and organization?; LisaNova nails a Hillary/Sunset Blvd. impression; Surrender Hillary is popping up across the land; two candidate Twitter feeds aggregate Twitter-chatter about the candidates; and George Bush submits to his first online-only (but not live) interview.

Bob Barr, who served in Congress as a Republican but is now registered with the Libertarian Party, today formally announced his entry into the Presidential race, and as the only candidate for his party’s nomination who has actually won a significant election, will likely be the Libertarian candidate this fall. Can Barr harness the energy from the libertarian-minded Ron Paul campaign and mount a disruptive third-party run? Or is he doomed to receiving a miniscule portion of the popular vote, as has been the case with past Libertarian presidential candidates?

Update: This post has been changed to clarify the paragraphs speculating on the acquisition of the Ron Paul list.
