The G.O.P. Fails Its Super Tuesday Trump Test

“Just five days ago, we began to unmask the true nature of the front-runner so far in this race,” Senator Marco Rubio, of Florida, said, in Miami, on the night of Super Tuesday—a night that ended badly for him. “Five days ago, we began to explain to the American people that Donald Trump is a con artist. And in just five days we have seen the impact it is having all across the country.” Rubio has been running against Trump for eight months, which raises the question of why his unmasking efforts had waited until last week, and what evidence he has that his attacks are working now. By the early hours of Wednesday morning, Trump was declared the winner in seven states: Alabama, Arkansas, Georgia, Massachusetts, Tennessee, Vermont, and Virginia. Senator Ted Cruz, of Texas, won his home state, as well as Oklahoma (which was one of four on the Democratic side that went to Senator Bernie Sanders) and Alaska. Rubio won only the Minnesota caucuses.
