More responses from Republican National Convention attenders responded to my question: What’s your best guess of Donald Trump’s percentage of the popular vote in the November election?

David Brooks, New York Times columnist, says 40 percent. “He’s been at 40 forever” in the polls, he says, which is not far off the mark. In the RealClearPolitics average of recent polls, his support in two-way pairings against Hillary Clinton has ranged from 38-44 percent.
