There are several reasons why I'm not too upset about what happened last night
1) Obama is still president- True, he won't be able to get much done, but he will still act as an important firewall to whatever insane bills the new GOP congress pushes through. I actually welcome them to try to craft legislation that reflects the demands of their Fox News watching constituents. Only then will Dems who sat out last night be convinced not to make the same mistake again.
We'll see whether his veto pen gets much use, or if he continues thinking that we're in a "post-partisan era" and need a "grand compromise".
The Democratic party clearly showed that it's the overly complacent party. It takes its voters for granted, while failing to taking the lead in arguing why Democratic ideas are better. It has failed to stand up to Republican attacks.
If there's a Democratic President in 2018 who isn't any better at leading than Obama, it will be another bloodbath for the Democrats.
Things didn't go that well outside of the south, either.
