Though he had lifted the title of his August anti-Trump polemic, "Conscience of a Conservative," from Barry Goldwater, Jeff Flake is no Barry Goldwater.

Goldwater took on the GOP establishment in the primaries, voted against the Civil Rights Act of 1964, defiantly declared, "Extremism in the defense of liberty is no vice," and then went down to defeat battling to the end after the assassination of JFK made LBJ invincible.

The real "Mr. Conservative" was a true profile in courage.

Flake, with only 18 percent approval in Arizona, decided to pack it in rather than get waxed in his own primary. With Falstaff, Flake appears to believe that "discretion is the better part of valor.".
