With early voting fast approaching, the rhetoric by Republican presidential nominee Donald Trump has turned more ominous with a pledge to prosecute anyone who “cheats” in the election in the same way he believes they did in 2020, when he falsely claimed he won and attacked those who stood by their accurate vote tallies.

He also told a gathering of police officers last Friday that they should “watch for the voter fraud,” an apparent attempt to enlist law enforcement that would be legally dubious.

Trump has contended, without providing evidence, that he lost the 2020 election only because of cheating by Democrats, election officials and other, unspecified forces. On Saturday, Trump promised that this year those who cheat “will be prosecuted to the fullest extent of the law” should he win in November. He said he was referencing everyone from election officials to attorneys, political staffers and donors.
