The last debate all but eliminated Castro as Veep
I think just the opposite. It certainly ended his presidential aspirations for this cycle, but as an audition to be Warren's running mate it was a huge success.
I prefer Beto due to Kennedy campaigning with Beto, for Beto's Senate race. GoP counts out Beto as well as Warren, but it will be great for two comeback kids to be on the same ticket.
Castro, Buttigieg and Beto will be vying for Veepstakes. If Biden is nominee, hopefully he takes from this list as well
Honestly I don't like the idea of picking a VP from this sold out train of failed candidates, except inslee if we can somehow intimidate him into having charisma
