A caucus is something people vote in. Sort of a small booth. An overwhelming favorite is a candidate that often comes over to the convention and whelms the delegates. The jobs of delegates is to resent their states. Noncommittal is to be able to talk and talk without saying anything.
Political science is to try to figure out what makes candidates act that way.
When they talk about the most promising presidential candidate, they mean the one who can think of the most things to promise. Political strategy is when you don't let people know you have run out of ideas and keep shouting anyway. A candidate should always renounce his words carefully. We are learning how to make our election results known quicker and quicker. It is our campaigns we are having trouble getting any shorter.
