Nobody is trying to silence him, but he gets more air time than just about all the other candidates combined. When he says something substantive, by all means it should be reported. But stop covering it every time he babbles or whines or hiccups. The man can afford to pay for that coverage.
Are you suggesting that the current front runner of this election, who decided not to take the bait and show up at yet another debate, is NOT news?
Interesting perspective.
