Rather, the primary issue is that netroots activists and TNR have major, persistent, principled disagreements about foreign policy. ~Matt Yglesias
That often seems true (certainly it is true when it comes to Iraq). I certainly hope this is the case all of the time, though the unfortunate enthusiasm of some progressive bloggers (who are, I understand, not part of the “netroots” proper) for Obama’s recent foreign policy address makes me think that this may be exaggerating this disagreement.
Update: A Kossack expresses his displeasure with Obama on foreign policy, so maybe there is some hope for them. Matt Stoller characterises it by saying it was “what I would expect from a brilliant neoliberal,” but nonetheless finds “a lot to like here, though it’s not so much a progressive vision.”
