Should the also rans drop out and make it a Biden/Sanders contest?

[Celerity]

12. After Super Tuesday none of the 3 have a path. Especially Klobuchar.

Other than the irrelevant Gabbard, Klobuchar is dead last of the remaining candidates in almost every state, except for MN, with MN being the only reason she is still in (to block Bernie). She also, along with Bloomberg, pulls mostly from Biden, more than the others, Pete included. As for Warren, there is a high likelihood she doesnt even win Massachusetts and has no real path either, barring some freakish turn of events (Bernie becoming ill, etc)

Pete will do the right thing, but that same call to drop out surely also will apply to Klobuchar and Warren as well.
