I agree with you that Joe Biden is not corrupt.  In fact, I'm surprised that Ross expressed Trump's talking points about him.

About Sanders:  As much as I agree with his positions on health care and education, I just don't think he is electable at this point in our evolution as a country.  Socialism by any other name is still associated with Communism; and Trump will pound that home to both his base as well as to those Independents and moderate Republicans who voted for Democrats in the 2018 congressional races. 

I worry too that Biden will be hit with fake information out of Ukraine, compliments of Guliani who's already told us when answering Trump, that he got more information than he expected.

Fox news will hammer that over and over.

My pick for Biden's VP  would be Kamala Harris, although I can see your argument that Elizabeth Warren would take some of Sanders' votes.

I now this:  I don't want Hilary Clinton, or her husband, anywhere near the decision making at the convention.  

I think Bloomberg could beat Trump, but am uncomfortable with his Wall Street loyalty.

Ha, my computer insists on little t for trump.
