They’re shifting even further to the left

you're not wrong,but I find it funny that everyone labels the democrats as "left" when they have been anything but for over 20 years.

and if anyone on the left actually buys the establishment democrats obvious appeal to principle (hahaha,democrats and principle) then you are right.

they deserve everything they get.

Regular traditional Democrats typified by Bill Clinton are finding themselves displaced more and more by radical leftists in the party. The Tea Party pretty much did the same thing to Republicans.

bill Clinton flipped the script on traditional democrats.
NAFTA?
3 strikes?
demolition of the welfare system?

the courting of big monied interests to combat the cold efficiency of the republican donor machine.

while politics has ebbed and flowed,and we can point to certain "eras" where ideologies shifted,for both repubs and dems.
bill Clinton and his administration almost singlehandedly destroyed "traditional democrats" and he sold the American worker down the river.

seriously,the Clintons are going to burn in hell for eternity for their utter,and blatant betrayal of not only the American people but the core principles of a party who,if they do not dadapt and evolve...are finished as a party.
