Broadcasting live from Wichita State University, Morning Joe’s Mike Barnicle sums up the numbers behind the latest NBC News/WSJ poll, which shows Republican presidential candidate Ben Carson leading Donald Trump with 29 percent to 23 percent, respectively. “Fifty-two percent of the Republican electorate polled are either with Trump or Carson and you have to believe that the rest of the numbers are tremendously fluid around several different candidates.
