The Democratic National Committee deployed a new anti-Mitt Romney viral video today that drives home the point that the former Massachusetts governor is a serial flip-flopper, interspersing clips of the candidate’s media appearances with late-night quips from Jay Leno and Conan O’Brien. But the spot is the latest in a trend among campaigns to mimic movie trailers, heavy in the use of pithy phrasing and provocative one-liners. It’s certainly not novel: Tim Pawlenty used the trailer approach in a series of web videos that had the feel of a Jerry Bruckheimer presentation, perhaps a bit too over the top for a candidate who struggled to get traction. A shorter version of the spot is running on air in some swing state markets.

The Romney campaign immediately dispatched Pawlenty as a surrogate to counter-attack, and it hosted a total of 12 conference calls to refute the attack.

Pawlenty said in a statement, “President Obama’s policies have been utter failures for the middle class: he has failed to create jobs and has burdened future generations with massive amounts of debt. This Administration does not want to campaign against Mitt Romney and be forced to defend three years of failure. Instead of focusing on the middle class and job creation, President Obama and Democrats are focused on campaigning and trying to tear down Mitt Romney.”

Quotable: Peter Bart slams Romney in his latest Variety column. “The Romney campaign keeps playing like one of those soggy sitcoms that the networks canceled one or two seasons ago and that accidentally got plugged into the schedule once again.”

Occupy Update: The media’s attention is now on Occupy LA, where protesters are fighting plans for eviction from an encampment around City Hall. Once again Michael Moore provided a running commentary on efforts to oust those tenting on the lawn.

Her View: Scarlett Johansson calls Occupy “important,” but tells Arianna Huffington in the latest Interview magazine that “yes, people are fed up—and I think quite rightfully so. But what are they proposing as an alternative to just being upset or feeling disillusioned or abandoned? That kind of protest movement really needs to happen on a much bigger scale, but there needs to be a clearer message.”
