Check out this little tidbit in that Politicker item I linked to below about Barack Obama's big foreign policy speech planned for Tuesday. The item quotes Obama foreign policy adviser Samantha Power as follows:

Power also contrasted what she said was Obama's effort to look forward with the foreign policy attitudes of his Democratic rivals John Edwards and Hillary Clinton, who she suggested was stuck in a 1990s view of the world, when American influence was much greater.

"Edwards is less prone to this than Hillary," she said, adding "Let's be clear, those tools that we got away with by the skin of our teeth are not the tools that are going to work in the 21st century."

That's actually a pretty sharp criticism of Hillary, and a jab (though a softer one) at Edwards, too. There's nothing wrong with that, of course -- vigorous debate about foreign policy ideas should be part of the campaign, natch -- but it's worth noting that the last time an Obama adviser publicly criticized Hillary, her campaign went ballistic. Wonder if they'll respond to this one.

Update: Interestingly, Power is clarifying that her remarks about Hillary and Edwards don't represent the views of the Obama campaign. The Politicker has added the following update:

Samantha Power asked me to clarify that her comments about Clinton and Edwards are her personal opinion as a professor of US foreign policy, and that she was not speaking in her capacity as an advisor to the Obama campaign.
