Donald Trump loses temper in Twitter exchange with Modern Family writer

I had a big smile watching Modern Family writer Danny Zuker runs comedic circles around Donald Trump on Twitter. The presidential candidate's rejoinders to Zuker's spot-on zingers consisted of name calling -- "boring," "moron," "loser," "very dumb," "stupid."

I've felt embarrassed for Mr. Trump many times. This is the first time I felt sorry him.
