… As we head into the fall it’s fair to ask—is the Democratic field set? Or not? On the Republican side it probably is—with seventeen candidates in the race there aren’t many people who are not running for president. But in spite of all the talk about other candidates on the Democratic side that field is probably set as well. Putting aside the question of how serious Hillary’s problems are (I, for one, am not in the “bed-wetter” camp that is easily panicked) there are serious structural problems that will, very shortly, keep anyone who is not already in this race from getting in. CONT.
