It has become thunderingly obvious that Warren has no path to the nomination. There will be no brokered convention and no successful unity candidate. So what now?
She could drop out and throw her support to Sanders, of course. The other possibility would be to maintain just enough of a campaign to qualify for the remaining debates and to use her speaking time to annihilate Biden. Bernie doesn’t have the skill to do that, but she does.
Would she try it? It would mean burning her bridges with most of the rest of the party. The safe bet would be no. The possibility cannot be entirely dismissed, however.
