How would a battle b/n Castro, Booker, (and a 3rd candidate) play out?

How would a Battle between Castro, Booker, + whoever emerges as the 3rd Person ... play out regarding Primary Votes... (assuming Booker is the only Afr Am in the Primary)

I'm thinking it could end up being a pretty close 3 way battle (I don't think there has ever been a really strong AA & a really strong Latino candidate in the Primary at the same time)...

Castro would likely be strong in :TX, NV, NM, FL, CA, CO, AZ

Booker would likely be strong in:NJ, NY, AL, MS, GA, SC, NC, TN, MD

3rd Candidate: likely strong in the Midwest & upper NE (more states... but not many large states left)

Depends on the third candidate. Al Franken?

I was thinking Franken, Brown, or Warren could emerge as the 3rd candidate..

Playing with the numbers... its hard to tell how the votes may fall if you have Booker, Castro, (Franken/Brown/ or Warren)

What if the third Democratic candidate is Bernie Sanders?

I think Sanders & Clinton both know that either of them running again would be too divisive for the dem party
