I only saw highlights from last night's debate, but what I gathered was...
The Winners: Elizabeth Warren, Bill DeBlasio, Tulsi Gabbard, Corey Booker
The Losers: Amy Klobachar, Beto O'Rourke, John Delaney, Tim Ryan
Neutral: Jay Inslee, Julian Castro
The losers should be exiting stage right very soon. Just like their poll numbers they offer and amount to nothing. They are trying to outBiden Biden, who has been tanking in his frontrunner status in the polls since he announced. If they want to go down that rabbit hole, by all means do so.
EDIT: Latest poll has Warren surging from 3rd to 2nd place, only 6 points behind Biden. I'll make a prediction and feel free to quote me on it later, but Biden is not going to be democratic nominee, he won't be the frontrunner past this Summer for that matter. He will continue to put his foot in his mouth saying dumb, ignorant things and flame out like he has the last 500 times he's run for president for the past three decades.
