Apparently, #Sanders is not bringing in new voters and seems to be pushing existing voters away. (I haven’t yet seen results from #TX or #CA, so their analysis may be too early.)
@lnxw37a2 But keep in mind that Warren is still running and probably siphoning of votes from Sanders or rather preventing Sanders from getting her voters. (A main reason why pressure on Warren increases.) So perhaps due to Warren (and, of course, a stroing Biden) Sanders cannot "bring in" more new voters.
