Considering that Hillary is likely to have a couple more big wins coming her way I don't see why she would drop out at this point. And while you want your guy to win, he hasn't yet nor is he entitled to it just be given to him. Hillary will likely finish the process with more people having voted for her & be positioned as the one who would do best in a general election & it's electoral college.

BTW I don't blame Obama for going with the spin that he's simply to busy to be able to campaign in Kentucky. It looks like another huge loss by voters who are still interested in voting for Hillary Clinton.

Fair play!
