Is This Huntsman ad the best way to attack Romney?

The campaign of former Utah Gov. Jon Huntsman has released a video that portrays former Massachusetts Gov. Mitt Romney as a man who chooses his positions based on the way the political winds are blowing.

In a minute and a half long ad called “Weather Vane”, Romney is seen changing his position on a number of important topics. This includes everything from health care to economic stimulus. While the clips of Romney are playing a video of a moving weather vane can be seen on the split screen.
