this is wishful thinking(aside from biden) more than it is realistic, but I do hope you are right.The debates will change everything. Beto is a skilled orator. Is that enough? Hell man IDK. But early coverage like this is pointless. He remains one of the stronger candidates in the field - in the top third - regardless of whether he's lost his "lead" or not, whatever that means.
Flaming out after the first debate, or maybe 2+ debates if they're jerks about it:
Delaney
Gabbard
Gillibrand
Hickenlooper
Inslee
Klobuchar
Hanging on a little bit longer but ultimately folding:
Yang
Castro
Outside but better-than-0 chance of actually winning:
Harris
Booker
Buttigieg (this may be underrating him)
Beto
Frontrunners
Warren
Biden
Sanders
...Basically, in my judgment out of the ~20 real candidates, ~7 are actually credible and that'll be the field that actually makes it to the primary, along with a couple of hangers-on that SHOULD drop out but won't. And Beto is absolutely one of those 7.
If it ever comes down to Warren and anyone else who isn't biden(shit even Klobuchar), i'm Gucci.
