And conservatives? Not so much...
A rational citizen, by definition, praises and supports political leaders only when they do the right thing (regardless of motive), and criticizes and opposes them when they don’t. It's just that simple. Cheerleading for someone because they're on "your team" is appropriate for a sporting event, not for political matters. Political leaders deserve support only to the extent that their actions, on a case-by-case basis, merit that support, and that has largely been the behavior of progressives towards Obama.
Hence: civil libertarian critics of Bush have vehemently criticized the Obama administration for embracing Bush’s secrecy theories, shielding government policies (including torture) from judicial review, denying all rights to Bagram detainees, and retaining some of Bush’s extreme detention powers, but have praised him -- often lavishly -- for restricting FOIA secrecy, banning waterboarding and CIA black sites, disclosing key Bush-era OLC memos, bringing charges against the last "enemy combatant" in America, and guaranteeing International Red Cross access to all detainees. Foreign policy critics have objected to Obama's escalation of our military presence in Afghanistan and drone attacks in Pakistan while praising him for preliminary changes in our tone (if not policy) towards Israel and his diplomatic overtures to Iran. Economic critics have attacked his bank rescue plan as a sleazy give-away to Wall Street and his excessive stimulus compromises, while praising his ambitious domestic budget and his core stimulus approach. In most areas, his record has been mixed, and thus progressive reaction to it has been as well.
The point, though, isn't so much the lockstep devotion to Bush among the conservative rank-and-file as it is the blindly uncritical, cult-like glorification of him by the Right's opinion-making leaders and their refusal to criticize what he did -- until they sought cynically to distance themselves from the stench of his failure late in his presidency (and anyone who doubts that should just click on the links in the first paragraph or read this). If one searches for it, one can find that devoted reverence towards Obama among some creepy cultists and overly eager supporters, but that has not been the predominant behavioral trait among progressives.Nor is it the behavioral trait among the progressive leadership and opinion-makers.
