Does Donald Trump lead the race for the Republican presidential nomination? Or does he lead it by a “yuuuuuge” margin? Bloomberg recently released a poll that gave Trump 24 percent to Ben Carson’s 20 percent. On the same day, Ipsos released a poll that put Trump at 37 percent to Carson’s 14 percent. Normally, I’d suggest you average the results and move on. But these two polls are emblematic of a deep divide this year first noted by Jonathan Robinson: The Bloomberg poll was conducted over the phone with live interviewers; the Ipsos poll was conducted online. CONT.
