evidence: Although former President Trump has spent years attacking the integrity of early and mail-in voting, his campaign and the Republican National Committee this week launched what they called a "huge" and "revolutionary" effort to encourage both methods of casting ballots in the battleground state of Pennsylvania. [...] In an interview with television host Dr. Phil McGraw that aired Tuesday, the same day Whatley’s statement went out, Trump said voting by mail "shouldn’t be allowed" and falsely claimed that "any time you have a mail-in ballot, there’s going to be massive fraud." [...] Despite the efforts of Trump’s campaign officials and the Republican Party, it is simply too late to rebuild trust in mail-in voting among the former president’s supporters by election day, said David Becker, a former U.S. Justice Department lawyer who heads the nonpartisan Center for Election Innovation and Research.
