Has been helping to lose this thing for Clinton since the start.  Her website remains largely nothing but a fundraising front and a place to put plan/platform details.  There's still very little that's actually helping to get people out there to  hear her, much less to vote.

"The question is not about picking up the phone," he said, referring to Clinton's new ad. "The question is: What kind of judgment will you make when you answer? We've had a red-phone moment. It was the decision to invade Iraq. And Sen. Clinton gave the wrong answer. George Bush gave the wrong answer. John McCain gave the wrong answer."

The Obama campaign also began re-airing a television ad featuring one of his prominent backers, retired Gen. Merrill A. "Tony" McPeak, crediting Obama with demonstrating the proper judgment in opposing the Iraq invasion.

Later, McPeak joined former Navy Secretary Richard Danzig on a conference call with reporters in which they poked fun at Clinton's claim to be the most experienced candidate. McPeak, alluding to turbulence in Clinton's campaign and Obama's comparatively smooth operation, said that running for president is a lot like marshaling a war.

"If you want to know what kind of commander in chief Barack is going to be, why don't you compare the campaigns that have been run here?" McPeak said. "Is it a panic situation? Crisis-driven? Are you firing people? Are you loaning yourself money?"

McPeak seems to relish the role of attack dog, and he would likely be a chief defender of Obama's security credentials in the general election campaign. In a recent interview, he suggested that he would not hesitate to take aim at even McCain, the former Navy pilot widely viewed as a war hero for the years he spent in a North Vietnamese prison after being shot down.

"In a perfect world, Obama might have a little more [experience], maybe even some service in uniform," McPeak said in the interview.

"But like I used to tell John: You don't get to be a hero by getting shot down, you get to be a hero by shooting the other guy down."

Also, most people think he's going to be the Democratic nominee, so negative attack on him might hurt in the general.  At this point with her, it seems less likely that his barbs will hurt her in her next election- reelection to the Senate in 2012.

50 state strategy means 50 states.  it might not be the best use of his time, but it shows his determination to the 50-state strategy.

He is going after every delegate everywhere as he has been all along. Clinton, in display of horrendous judgment, has focused on a very few states as if they were winner take all, and only 4 states on Super Tuesday. If Obama loses Rhode Island overall but picks up an extra couple of delegates by campaigning there, he realizes that it's better than outright ignoring the state as Clinton has done with 2/3 of the nation - which is why her turn from inevitability to unlikely is all the more emblematic of their comparative strategic planning and execution abilities.

It's also the case that there's truth to many of his attacks.  Clinton did call NAFTA a victory (in her book, iirc) a few years ago.  She did vote for a bankruptcy bill but "hope it wouldn't pass."  (Still waiting for an explanation on that one!)  She did give W the authorization to go to war.

Clinton's attacks... it's true he's only been in the senate 3 years and failed to convene his minor committee chairmanship.  I'm not sure what else she has to go after him with.  The "present" attack, for example, is intellectually dishonest.

You may agree with her assessment, I don't.
