Philip Bump: “For months, Trump had been touting a 93% approval rating from Republicans. The first iteration of that figure that we found came from a straw poll conducted at the Conservative Political Action Conference, which is a bit like foxes claiming to be overwhelmingly popular after surveying people at a furry convention. It’s like asking about support for the Second Amendment at a gun show.”
“In June, though, Trump tacked on a percentage point. He first claimed to have 94% support from Republicans during a news conference with then-British Prime Minister Theresa May. Our fact-checkers looked into it, determining that there was no public poll showing anything of the sort. If it was an internal campaign poll, it hasn’t been made public (our fact-checkers asked). Since then, though, 94% has supplanted 93% in Trump’s rhetoric, with his touting this purported number
“Trump appears to simply be making the figure up. Perhaps there is internal polling showing Trump with substantially higher approval than public polls, a function of who they’re asking and how they’re asking it. But Trump doesn’t even say that; he just throws out this number as though it’s real.”
