Trump leads in national Monmouth poll. Only Ben Carson has a higher favorability rating.
This poll is just now breaking so please excuse the copy and paste. The bottom line is Donald Trump has surged to 30% in the latest Monmouth Poll. On a more provincial note, Ohio wunderkind John Kasich has dropped to 2%. While Trump is at his strongest Jeb Bush has reached his lowest polling numbers in the history of the poll.
In the favorable / unfavorable table Trump leads everyone except Ben Carson whom supporters would probably rather canonize than elect as president.
