Do you know what it means to be co-opted?
I do not believe that Bernie Sanders will ever get over the communist/socialist stigma of his past statements and positions and be electable in this country.
This is a guy who lavished praise on the totalitarian government of Venezuela in 2011, a position he later recanted. I saw how that government worked out. I believe that he would be as divisive as our current president and our country needs something else right now.
Joe Biden is not a perfect candidate. They don't exist in the real world. He is prone to verbal misstatements. But I think that he is the same guy he always was and I think he would put very able people in position to keep our government running effectively and who will make sure that he is making rational decisions.
In the worst case scenario, I would take your mad Uncle Albert floating on the ceiling over the current malignancy inhabiting the White House any day. As noted by the excellent piece in the New York Times by Frank Bruni, Bernie Sanders has already won, Sanders has changed the national political conversation and the other current candidates are all now ideologically to the left of predecessors Kerry, Obama and Hillary Clinton.
You can of course, also thank Trump for that, his extreme positions, flat wages, income inequality and the lack of any pretense of moral conviction having so greatly exacerbated the cultural war and political divisions in our country. I think that Biden might be able to make at least a small step to heal them. If Sanders gets the nod, I will back him, I hope that those on the left will not hand the country back to Trump because they got a sniff and it didn't go their way.
