President Trump claimed in his State of the Union address on Tuesday night to have ushered in a "turnaround for the ages" by citing a list of familiar falsehoods and inaccurate claims. In nearly two hours of remarks, Mr. Trump sought to persuade voters unhappy with his handling of affordability and immigration enforcement that the economy was "roaring" and that deportations were focused on criminal migrants. And he again sowed doubt in the upcoming midterm elections by repeating falsehoods about "rampant cheating."
