Would having Mrs Warren on the ticket in 2020 doom the Dems?

I am not counting any chickens before they are hatched. The news media will be for the Dem candidate, no matter who they are. The percent of people wanting socialism is growing. The Deep State can produce "dossiers" or accusations anytime they want to sway things. There is an enormous amount of voter fraud that can swing things. There is certainly no room for complacency.
