Old politics in new bottles
I do disagree with Glenn on one thing, which is his presentation of several either/ors — such as closing Guantanamo or not, repealing DOMA or not — as proper tests of Obama's progressive fealty.
Closing Gitmo isn't the same as ending the kangaroo-court tribunals and related debased forms of American "justice." Repealing DOMA isn't the same as legalizing gay marriage. Even "withdraws from Iraq" could mean any of several scenarios (such as leaving all our mercenaries in Iraq) that would provide bragging rights but false or insufficient change.
As America's Anti-Manichean-in-Chief, Glenn surely realizes that Obama may quite possibly do a few high-road symbolic acts and still not bring us serious progressive reforms. If we over-invest in those symbolic metrics, then — if it turns out that Obama cares what progressives think to some heretofore unseen extent — we may well get those and little else.
