On today’s edition of CNN’s State of the Union, Senator Lindsey Graham (R., S.C.) suggested that voters who are impressed by Donald Trump have “lost their way,” and that those Republican presidential candidates who believe that Trump is “speaking the truth” are wrong. Trump, Graham claimed, is a “demagogue” and a “wrecking ball” who is miscasting the problem of illegal immigration and hurting the GOP in the process.

The United States, Graham proposed, needs to make “order out of the chaos.” But it must do so sensitively. Donald Trump believes that “most illegal immigrants are criminals” and a few are “good people,” Graham said. But in truth it is the other way around: most illegals are “good people” and a few are criminals.

Repeatedly, Graham described Trump’s candidacy as presenting a “defining moment” for the Republican party. The question, he asked pointedly, is no less than whether the GOP will maintain the “moral authority to govern the country.”
