Handicapping these:
Cory Booker: Leading the charge on Trump impeachment. That and the fact that he has essentially the same qualifications as Obama had means he stays in.
Julian Castro: Mayor to POTUS in one, giant leap? Nah, too big a stretch. He’s out.
John Delaney: “Corporate” is the Kiss of Death in the AOC-ized Democrat Party of 2020. He’s out.
Tulsi Gabard: Too pro-gun and has not supported gay marriage in the past. Definitely out!
Kamala Harris: High melanin level + a vagina assure she’ll be slugging it out all the way to the convention. She’s in.
Amy Klobuchar: Hillary Clinton’s personality with a Sarah Palin accent. Ugh! Definitely out!
Bernie Sanders: For whatever reason the Millenial kiddies who are pining away for socialism view him as their favorite uncle. The trends don’t favor owners of white penises this cycle, but I say he stays in.
Elizabeth Warren: The Fake Cherokee fiasco would appear to have dealt a death blow to her campaign. Unless banks do something amazingly stupid to p*ss people off and get them clamoring for public floggings of bankers at Yankee Stadium, she’s out.
Marianne Williamson: Who? You’ve got to be kidding. Out!
Andrew Yang: Out for the same reasons as John Delaney above.
Pete Buttigieg: I kind of wish he’d stay in if only for the fun of hearing talking heads say Buttigieg every day. But out for the same reason as Senor Castro.
Kirsten Gillibrand: As the least-worst looking female Democrat I can think if she likely stays in.
Those you named who will stay in, will stay in until Hellary tells them to go!
Joe Biden is too much of an establishment stooge to count as out just yet.
