If Joe gets the nomination - the VP is crucial - I do not think Joe will last a 4 year term as POTUS due to his advancing dementia.
If he adds a Marxist VP to placate the radical Fascist DPST's of his party - this country could have a true marxist in Office.
My vote goes to bernie and/or lizzie - they radical marxist stands won't fly in Nov 2020! Radical Fascist DPST group needs a lesson !
