If Scarborough were to run for president, he could run against Trump as a Reagan Republican who does not praise dictators from Russia to the Philippines. He could run against Trump and promise he would not humiliate his secretary of State by proposing to cut the budget for the State Department by 30 percent, as Trump has done, or permitting a laughably inexperienced son-in-law to act like a shadow secretary of State, as Trump does every day.

Former congressman Scarborough could credibly pledge that after he has served in the White House for six months as Trump has done, he would be able to perform much better than Trump, who has been unable to pass through Congress even one major piece of legislation since January.
