Yup, fair point.
I would be interested to see left base tested like the right has been. And see if they would put up with all the fascism, racism, sexual assault, serial lying, corruption, criminality, constitution defecation, collusion with a hostile foreign government, personal gain at the expense of country and party, bullying, thin skinned bitchiness, assclownery. I suspect the left's base wouldn't be as big- maybe 10-15% not 37%.
