It really is weird. It's brought the Authoritarian liberals and conservatives together in support of the government doing the right thing, and freedom-loving liberals and conservatives together in opposition.
The support and opposition are both very much bipartisan affairs, with the vast bulk of people seeming to just want to cover their ears and eyes because they don't want to know what the government is up to.
Regardless, at least here in New England pretty much every liberal I know who actually follows politics dislikes Obama now, primarily because of this. Many of them don't want to talk about it because they are afraid of being lumped in with the uber-crazy conservatives who constantly launch irrelevant vitriol his way (usually while supporting him on the things he actually fucks up) but there is a lot of grumbling and general desire for an alternative - but people don't know what to do. What IS the alternative? Obama was supposed to BE the alternative - he promised everything they wanted, they voted for him, and he... turned out to be everything they hated.
What can they do? What can they actually do? I get the feeling that for anyone who is politically aware, they are just frustrated and they've had their hope, the thing Obama sailed in on, dashed. What's the point of getting angry and upset? What's the chance it actually changes something this time, when it hasn't before, and your ostensible allies the low information voters who go for the straight party ticket, your silent base of support, are now essentially your enemy because they just don't care about anything beyond keeping the Republicans out?
