We have the votes out there on issues. Those issues are decidedly left in some cases. We have a political party that has maintained a center right centrist position. Much of that dominance has been by active thwarting of left candidates. No left candidates, no votes.
I'm maintaining the point that, until very recently there has been no left wing political representation and to call most members of the current Democratic party as being 'Left" is nonsense.
However, if you narrow the scope of conversation and issues to confine the meaning of whats 'left' then you can get away that kind of nonsense being 'left'.
I'm calling B.S. is all. Your not 'left' if you think renting your chicken coop to the elderly poors is a progressive left solution. Know your enemy.
