I would think if progressives wanted an old rich white person whose dubious achievements are mostly having the right name and connections they could just stick with Hillary.
Hillary doesn't have the humour value of Trump. The man is entertaining in the same way that a flaming clown car careening off of a bridge and crashing into a fireworks factory is. Sure, it's horrific and tragic and all that, but it's also kind of funny and the fact that you feel kind of bad about enjoying watching it doesn't make watching it less enjoyable.
