Hillary Clinton's biggest problem right now isn't her lack of money, and it isn't that undecided superdelegates will suddenly move against her. Indeed, yesterday was notable for the fact that so few superdelegates declared, and that multiple Democratic party bigwigs went public saying Hillary has every right to stay in the race and shouldn't necessarily get out just yet.

The biggest threat to Clinton's candidacy right now is the media, and the instant (and almost universally accepted) conventional wisdom among the pundit class that it's over. Yesterday Clinton suffered through a barrage of political obituaries, from talking head heavyweights like Tim Russert and George Stephanopoulos to opinion columnists from across the political spectrum.

That assault continues today with editorials from the Los Angeles Times (Clinton Can't Win), Boston Globe (Clinton Doubles Down....Why?), the Philadelphia Inquirer (Clinton Campaign Running in Place), Pittsburgh Post-Gazette (End Game: It's Time For Superdelegates to Speak Out), and the Chicago Sun-Times (Face It, Hillary: It's Over), and biting columns from George Will, Nick Kristof, Rosa Brooks, and Mike Lupica, to name just a few. (UPDATE: As you can see, the new cover of Time Magazine isn't helping matters for Clinton either.)

Equally as damaging are the wave of editorials and columns that cast her out of the picture and look ahead to the general election: Washington Post (Obama Moves On), Dan Henninger (Obama vs. McCain: Let's Get it On), Karl Rove (It's Obama, Warts and All), etc.

I could go on, but you get the point: the pressure is intense, the CW nearly set in stone. To continue Clinton has to somehow manage to withstand the former and defy the latter, which, needless to say, is a very tall order.
