Schumer is part of an old american politics where there was a cordial relationship between both sides and the cost of sacrificing the interests of the constituents was largely negligible - no one knew what was going on so no one could complain (pre-24hr news cycle and pre infinite news outlets online or in public). Times changed. People notice everything. Schumer is not built for this time where everything he does is under a microscope and where consequences are seen and felt. He is acting as if he can just pretend that things are like they were in the 90s where he can show up, gladhand with donors and his colleagues across the isle, cash a check, work 4 months out of the year, and insider trade. He cant. The problem is that he is also intrinsically part of the democratic party machinery so no one can force him out. He needs to be primaried at a minimum.
