Today, the Obama campaign put out the second video that directly attacks Mitt Romney's lies about President Obama using President Obama's own words. It's a strong political commercial:

There's nothing better in a political advertisement than when you catch your opponent in a lie, and these videos do that over and over again. (You can find the first video here.) The trick will be in getting these videos seen by the right people. Democrats will love them, of course, because they play to their interests. Far-left progressives will see them as more evidence that President Obama is leaning rightward on all the wrong issues. Republicans will do a step-by-step fisking of the points to prove that Romney was right all along. But these commercials need to be seen by independents and moderates, and hopefully the DNC is working on building a reliable framework for getting their materials out there. It sounds like they're building a network to do just exactly that.
