Harold Simmons' Obama Ad

Is it fair for a US citizen to pay for and air spots like this that are critical of a candidate's affiliation with an unrepentant anti - American terrorist? The Obama campaign didn't think so, so they whined to the DOJ to try and get the spot removed and the financier, Harold Simmons in a jam. Of course they only succeeded in bringing attention to the ad, which shows how Obama clings to the paleo radical Bill Ayers. If there are any inaccuracies in the ad, I'd love to hear about them. The lack of denial from the Obama camp is deafening.
Every American voter should see this ad, consider making a donation to the American Issues Project.
