John Cassidy of The New Yorker reminds us that the contest here, "as in all the other [five] states that will vote on Tuesday, isn’t a winner-take-all affair, meaning the delegates will be divided in proportion to the votes. Still, the outcome of the California primary is important. If Clinton wins, Sanders will come under pressure to fold his tent and endorse her. If Sanders wins, he may be encouraged to keep going all the way to the Convention in Philadelphia next month, which would greatly complicate Clinton’s efforts to unite the Party."
