Seems strange.  How do you vote for someone who is not running, a la Cruz and Rubio?  Seems to be a default position that your votes can only go to the one running.  Regardless, who cares, except Democrats, this is nothing more than a "feel good" rally.  I'll bet all the Alaska votes at the D party go to Clinton even though many Alaskans preferred Sanders but we won't hear much about that.
