Assuming Biden does in fact win Texas, this night went basically as well for him as it conceivably could have. Everything came together, from the withdrawals and endorsements by Buttigieg and Klobuchar, to the surge of late-deciding voters backing his candidacy in a diverse set of states, giving him a broader coalition. The race is probably far from over, but Biden may now be the favorite. Yet there are still a lot of contests to come, including some big ones on March 10 and 17, and I think it'll be important to see whether it becomes a true head-to-head race between Biden and Sanders or whether things continue to be more fragmented, with Bloomberg and Warren staying in.
