Joe Weisenthal explains why it fizzled out:
In 2011, Professors Michael T. Heaney and Fabio Rojas published a study titled: The Partisan Dynamics of Contention: Demobilization Of The Antiwar Movement In The United States 2007-2009 which looked at nearly 6,000 surveys of anti-war demonstrators between January 2007 and December 2009.
This one chart [above] basically tells the whole story. The percentage of Democrats attending anti-war protests collapsed at the end of 2008, and in early 2009. As Democrats are the biggest block of any of these groups, this desertion of the Democratic party was the major blow.
Garance thinks Democrats may oppose Obama:
Obama never has to stand for election again, but the jockeying for 2016 is well under way. It’s possible Obama’s intervention in Libya would have earned louder opposition from Democrats and liberals if the president had not also still faced reelection, which doubtless tempered some voices. That he won’t again opens up the floodgates of criticism from people who expect to be standing on the political stage long after he is gone, as well as by some who hope to take his chair.
Pareene, on the other hand, doubts that Democrats will take a stand:
[A] Syria campaign probably won’t create the conditions for a future Obama to stake out an opportunistic left-wing position and ride it to the presidential nomination in 2016. Americans won’t be dying by the hundreds and we won’t be committing ourselves to a drawn-out and bloody occupation. (Well, let’s hope we won’t be, I guess.) We’re going to launch missiles for a few days and then quit, according to the latest plans. That’s not quite a war you can hang a presidential campaign on. Probably not even a congressional campaign.
Right now liberals (and the political press) are letting people like Rand Paul meet the demand for America to have a less “muscular” foreign presence. (This isn’t really surprising: Liberal antiwar voices are pretty much always marginalized in the United States, by both hawkish Democrats and the press,) The right-wing interventionists are terrified at how much his position resonates with people. But I’d put money on the next presidential election involving two supporters of military action against Syria
