Gerald Seib: “The good news for President Trump is this: There just might be.”
“The bad news for the president: The universe of potential hidden supporters is heavily populated with the kinds of people who happen to be more comfortable with Joe Biden than they were with Hillary Clinton four years ago.”
“The question of whether there is a submerged Trump vote is rising in importance as virtually every poll, nationwide and in swing states, shows Mr. Trump losing to Mr. Biden. Nationally, the Biden lead is so large that the emergence of pockets of secret supporters alone probably wouldn’t be enough to fully turn around the numbers.”
