I feel like typically politicians on all sides vote for the 1% on too many economic issues. However, I do feel we need democrats and liberals in office to rollback many of the laws the GOP and conservatives are pushing through on social issues. As Rachel Maddow is fond of pointing out, despite the population becoming more liberal on many issues, as long as the GOP controls so many state legislatures they just keep pandering to the socially conservative bases.
Roe v Wade may still be the "law" of the land, but we can clearly see what states are doing to regulate clinics that provide abortions out of business.
I also see the democrats in my state anyway as being better stewards of the environment. I won't say they are all friends of the Sierra Club, but even the meager common sense regulations that were in place to help places like the Everglades have been rolled back or are not funded by the current group of republicans in charge. There's so much work to be done on all fronts and all over, not just certain regions.
