At The Washington Monthly, TDS Managing Editor Ed Kilgore flags and comments on Nate Cohn's "must-read" New Republic article "Why Romney's Money Advantage is No Game-Changer," noting:

...You can expect Team Mitt's closing ad barrage to be even more negative and mendacious than it's already been. Other than maybe a loud 'n' proud defense of the Ryan Budget that would lock the slippery Mitt into a clear post-election agenda (which pretty clearly ain't happening), the GOP base most wants a level of anti-Obama savagery that matches their own feelings. And it may be the only course of action with a chance of dislodging an unusually high number of undecided voters. Get ready for some Hateball.

A teaser from Cohn's post:

There's no way to be sure whether Obama will benefit from superior turnout, let alone whether it would overwhelm Romney's advantage on the air. But there's not much cause to presume that Romney's air campaign will pulverize Obama into defeat, either. The historical effects of ad spending are relatively meager, views of the president are deeply entrenched, and voters have already been exposed to a full presidential campaign's worth of advertisements. Even in the plausibly competitive states where Team Romney ran uncontested advertisements, millions of dollars do not appear to have put the states into play. Given that Team Obama maintains a lead after being outspent by a two-to-one margin for two months, there is no reason to assume that a deluge of advertisements will hand Romney the lead in the race's final hours.
