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.

There will be a lot going on in Pennsylvania today with the death match between Obama and Clinton coming down to the wire. A huge turnout and lots of new voters are expected which is always worrisome in large states like PA with lots of different municipalities (the Pittsburgh area has the largest number of unique municipalities in one county, Alleghany, in the country) all with their own machinery and rules. There will be a lot of commentary on who voted for whom, but there is another, smaller story worth watching, and that is what happens to the machinery tomorrow.

MySpace and NBC team up for mutual back scratching enhanced campaign coverage; Andrew Romano on headline-happy coverage from the campaign trail; MoveOn announces voting on voter-submitted pro-Obama videos; the Obama money bomb bombs; rural Pennsylvanians shopping at Cabela's prefer Obama to Clinton; IT pros on the election; a profile of Clinton's director of online finance and more confusion about voters and ATM machines; and the YouTubing of politics spreads to the London mayoral race.

Last night's debate is roundly criticized on liberal blogs; a new site asks Obama supporters to add their testimonials; a London Mayoral candidate will hold a live chat with voters; a nostalgic look at voter-generated video from Eyeblast.tv; James Kotecki gets serious; Obama is Apple, Hillary is Microsoft. Really?; Allison fine, co-editor of our Rebooting America project, will be interviewed live and online next week; and Hillary is following exactly ZERO people on Twitter.

TNR on the candidates' Wikipedia entries; email campaigns in PA reveal some odd choices; the first political meta-group in Facebook?; adding YouTube videos to a Googlebombing campaign; and Hillary launches a new PA-focused site and asks for a smidgeon of supporter input.

A new site collects voters' dreams about the candidates; tracking search trends in PA; Larry David sounds off about Hillary's "red telephone" ad; notes from a panel on how the netroots are changing politics; and Obama announces $55 million raised in February.
