Evaluation of Example 8: Romney's Audi Q7

Passage:

“Romney's post-election behavior has been, in a word, small. Never again, likely, will his voice and influence be as powerful as they are now. … The man who spoke passionately about his love for the American auto industry was driving around in a new Audi Q7. ”

Dana Milbank, "Romney Can Retire Later," Index-Journal 94 no. 220 (8 Dec. 2012), 9A.

Analsyis:

Mr. Milbank commits ad hominem (ex concessis) by noting that Mr. Romney's position on the American automobile industry is at variance with the automobile Romney chooses to drive.

Romney supported the U.S auto industry.
Romney now drives a non-American automobile.
Romney does not now support the U.S. auto industry.
