Pete Buttigieg, aka Alfred E. Newman, has suspended his bid for the Presidency.

…”a person briefed on Mr. Buttigieg’s plans said on Sunday, following a crushing loss in the South Carolina primary where his poor performance with black Democrats signaled an inability to build a broad coalition of voters.” (link)

The move to drop out makes sense within the most likely Club pattern to support Joe Biden.  Buttigieg drops out now ahead of Super-Tuesday allowing less fragmentation of the vote.  It will be interesting to see if he follows a Club plan to endorse Joe Biden because Buttigieg previously wrote high praise for Bernie Sanders.
Elizabeth Warren and Amy Klobuchar will stay-in to block Bernie’s delegate count in Massachusetts and Minnesota respectively (both states vote on Super Tuesday).  Klobuchar will likely drop-out after Tuesday.  Warren might follow.
