From Vanity Fair’s long, detailed, and brutal profile:
Desperate to keep his Senate seat, John McCain repudiated his record, his principles, and even his maverick reputation, entrenching himself as the anti-Obama. Which raises the issue of whether the leader so many Americans admired—and so many journalists covered—ever truly existed [….]
But it fell to Hayworth, a glib galoot who was twice informally ranked among the dumbest members of Congress during his 12 years in the House, to deliver the dead-on zinger that summed up where McCain has found himself in this strange and angry political season, struggling not to win the presidency but simply to hold on to the job which defines him, and which is all he has left. “It’s really sad to see John McCain, who should be revered as a statesman, basically reduced to a political shape-shifter,” Hayworth said.
So it is.
