I do not think I have seen anything like these ads. As a matter of style, they are very well done, and cutting edge. They have a political freshness about them. It likely explains why Brown has made the campaign competitive. Take a look yourself and ask the question if it appeals to you (disregarding any partisan pro or con–look at it as simply an ad).
At any rate, I think it works well. Perhaps we shall see more of these ads in 2010.
