One second you're all in on not fighting centrists and concentrating solely on repubs, and the next you are pretending that the battle for progressive outcomes has all but been won already. We wont see progressive outcomes soon, despite the won seats. The time to fight for those has now passed until the next election. You are too easily deceived. What you dont/cant understand is the number of congressman in both house and senate that AIPAC owns amongst the dems (and the repubs just as much I guess, but they as usual do not bear ta;kling about since we have no hope of changing them).
Dems are not your friends and they hate progressives. We needed to vote out centrists, but people like yourself always yell at everyone to do it later. Enjoy the next two years of being ignored by your own party, herr armchair-general.
