John McCain, to many the face of campaign finance reform in Washington, struggles to avoid the appearance of impropriety regarding recent donations by Cablevision to the Reform Institute, an independent group with ambiguous ties to the Senator. After his awful performance prostrating himself before Dubya in 2004, I’ve run sour on the mythical maverick — to paraphrase Progressive era Senator George Norris (R-NB) speaking of his colleague William Borah (R-ID), McCain “shoots until he sees the whites of their eyes.” But, still, he’s campaign finance reform’s biggest blue chip, and he should know better than to endanger the cause with this type of shadiness…particularly with anti-reform forces gunning for him. What would be plausible deniability for anyone else seems rather implausible coming from McCain, given his place at the head of the movement.
