Silver on contested convention

Nate Silver previously discussed this possibility here, noting that so many candidates in the race increases the possibility of no candidate getting enough delegates in the first vote. He also reiterated it last night after Bernie's huge NV victory on the possible motives of the other candidates staying in the race to the convention when he said:

"Sanders is by far the most likely Democrat to win the nomination with a majority of pledged delegates. Other candidates are mostly hoping for a messy outcome in which they win the nomination by plurality — potentially at a contested convention."
