I'm with Tiff on a few things, actually. After they called PA to Obama, I turned it off. PA was crucial to Romney and he had no shot in hell without it (not that he had a shot, anyway). Furthermore, elections really should be by popular vote, now, and not the electoral college. We have the technology and since the 2000 election, the popular vote has always been very close.
As was mentioned before, nothing changed on the federal level. Our only hope is that Congress saw how thrilled Americans were to see President Obama working closely with Governor Christie in New Jersey and that they understand WHY. Nobody gives a shit what party sponsored you - fucking work, asshole. Do your job.
The big "wins" last night were from the two issues I tend to lean liberally on - drugs and marriage (oh, how closely intertwined you are). Though I still don't understand gay people biologically and don't support their marriage economically, socially and ethically I couldn't be more for it. Talking with my wife about it, if/when it becomes a voting cause in Virginia, I'm going to vote for it. Sure, the taxes don't make sense and it goes against biology but that's not their fault and it's not their choice. As such, there's no good reason to prevent them from inheriting the fortune (or lack thereof) that they spent a lifetime building with their significant other. There's no reason to prevent them from being with their partner on their deathbed. The latter actually makes me sick to my stomach.
"Legalizing" marijuana in 3 states for recreational use is also a big win. Of course, federal law supercedes state but those states can and will actively decriminalize it and set a solid example for how to stop overcrowding our jails and ruining peoples lives over a recreational drug.
