I don't buy the "nothing changes" narrative about Obama's reelection. Yes, the landscape looks roughly the same in some important ways, but things are different, too.
For one thing, Obamacare will continue unchallenged, and the parts people really like will have a chance to kick in before the next presidential election. That's a big deal. And Obama, reelected in some part because voters recognize that lingering economic woes were not all his fault, will get credit for any economic recovery on his watch.
The message to the GOP on social issues is daunting: Republican hopes of winning the Senate, which seemed very realistic not long ago, foundered in some part on outrage over clueless comments on rape and abortion. Throw in changing attitudes on gay rights, and the trend looks friendly to Democrats.
And the demographic message was as clear as the glum looks on all those white faces in the Romney crowd last night. This is a big, diverse country, and you need to build coalitions instead of walls to win it.
I wouldn't overstate the magnitude of the victory, and of course a lot can happen in four years to give voters buyer's remorse. But all things considered, it's hard to spin last night as a meaningless win for Team Obama and the Democrats.
...adding, one other bit of good news for the Democrats is that their GOTV machine seems far superior to the GOP's -- not just in technology, where gaps can be narrowed if time and money are available, but in philosophy, which may be harder to change.
