Hillary wins PA, boxing metaphors take over the universe; John McCain is the ultimate winner of PA, and liberal groups keep attacking; Off The Bus provides the sanest coverage of the primary; Willie Horton ad-man Floyd Brown re-emerges; the Lieberman/Lamont hackery fracas rears its ugly head, again; Alan Rosenblatt live on Johnny's Par-tay tonight at 9 ET!; and the Obama campaign posts a video of... Chuck Todd.

The Ned Lamont campaign is cleared once again of hacking Joe Lieberman's site in August 2006.

It's become a parlor game for the chattering class: Who is ParkRidge47? TechPresident blogger David All has a great post up on his personal site that, at least for me, pretty definitively closes the door on the author being a mischief-making Republican. He tracked down an email exchange between ParkRidge47 and a person who had tried to post a video response on YouTube and had it rejected, and the language PR47 uses makes clear that this person is no friend of the GOP. Well, I have a different theory, which is that it's a professional--the language in our email exchange, and the proficiency of the technical work, makes it unlikely this is a kid. So, which professional?

Witnessing the continuing brouhaha over the 1984/Vote Different video, it's easy to think that the 2008 campaigns are the first to play with online video. For the sake of context, it's worthwhile to take a step back and look at how one previous campaign paved the way for 2008.
