The is the Democrats’ ad:

Both are very effective political ads, I think. The Dems’ ad is more clever (some would say cunning and manipulative) in that it attempts to marginalize the opposition as a bunch of crazies. The GOP ad is more substantive, in that it simply quotes the president’s ill-advised public statements about his health care reform agenda.

It remains to be seen whether either ad will resonate with the key bloc of independent voters not already committed to one side or the other in the health care reform debate. I think the Democrats have a bigger problem right now — angry voters nationwide — than the Repubublicans do. If the Democrats weren’t worried about the voter backlash they would not be trying to neutralize it.

In any case, this should be an interesting August.
