Why do reporters at presidential press conferences insist on asking long, convoluted questions that allow long, convoluted, meaningless answers? It's like they've already written half of their article and want to try it out on him.
Then they complain about the no-answer answers they get. Well, duh. Ask him something he has to answer.
Ask simple questions that cannot be spun, that demand more than just regurgitated campaign speeches. Yes or no questions are good.
