That is what the left wing said about a far right guy like Trump in 2016.
Until he won.
I consider the 'too far left' argument against Sanders to be bullshit.
what's your cut off point for too far left ?
we will assume Stalin, Mao, Josip Tito and Pol Pot are well beyond your limit for too left and thus too loonie
seriously think of all the dead people you would need to step over
Castro, Hugo Chavez ?
still too extreme left for you ?
ok what about these 2 clowns are they too far left for you?
Jagmeet Sigh, or Justin Trudeau?
Tougher question
Name one that has successfully run a country ?
Bernie Sanders would have made a god awful mess
