Unfortunately, I always find myself a little hesitant to spend a lot of time searching for documentary evidence that I'm skeptical exists, but other people claim *does* exist but can't produce.
For instance, a year ago, when I first started discussing the eligibility issue on obamacrimes.com, more than one person insisted they they personally witnessed Obama, on TV, say that he wanted to change the National Anthem to "I'd Like to Teach the World to Sing." They continued to insist having witnessed it even after it was pointed out that that story originated in a satire column. I offered to donate $100 to Phil Berg's campaign if anyone could produce this televised statement that they swore they saw on their own TVs, but I was only told to go search for it myself.
More recently, in his infomercial, Gary Kreep claimed that Alan Keyes raised the natural born citizen issue in a 2004 debate with Obama. Kreep specifically says that there is video of this event. But there's not. A representative of Keyes' own campaign has said no such event ever happened. So Kreep was just flat-out lying in the infomercial, and anyone searching for the video he cited would be wasting their time.
Now maybe your ad did exist. I admit I'm very skeptical, but I'm open to the possibility. A misspelled ad is not beyond the realm of possibility. But at the same time, I've lived through enough phantom evidence to not expend my efforts looking for evidence that others' claim exists but which they can't seem to produce themselves.
I spent hours and hours reading. You’re lazy, that’s fine. I’m not asking you to take my word.
Do your own research. It’s here on FR somewhere.
