This is my opinion only, of course
I want a female President. I voted for Hillary. I won't have any problem voting for either female candidate. But, I will vote for whichever candidate the Dems pick. I am voting Blue.
I think Mayor Pete has an uphill battle under load. I like him, but I am not sure he can win.
I think Trump did the job he set out to do on Biden.
The two billionaires: My first thought was, Oh Gawd, No! Two white, male rich guys battling it out. Plus, I don't know either one of them. But, Bloomberg is starting to grow on me. Why? He isn't going to run out of money. He says some obvious, non PC things about Trump that my heart responds to, and he seems like a hardnosed kind of guy that could punch Trump in the head. Also, I think that Trump will regard him as an opponent to be cautious with; the only thing we have seen yet is that the candidate is short. Trump has made up names to employ for his base, but, likely there are members of his base who are short, and they would be offended.
Those are the main candidates, I think. (Bernie aside.) I would like two of them to pair up as P. and VP, instead of picking an unknown as is traditional. This would require squelching ego in the best interests of the Country. Let whoever wins, win, then take the second winner and run that candidate as VP. Also could attach someone who dropped out, say Kamala, if that would work. Then you'd have two power houses to crisscross the country. They could be one step ahead of Trump/Pence.
