Not just that, he also blamed the birthers themselves, sneering, "It is far easier to air one's complaints via computer keyboard than it is to leave the comfort of one's home and actually make a physical effort." At least he realized that previous birtherpaloozas were embarrassing failures (case in point, Dr. Kate's "Usurpathon," which consisted of precisely three people) and didn't want his latest effort to fail just as spectacularly.
Interestingly, he cited a certain dentist (albeit not by name) and her minions as another reason to call it off:
"Even though the truth has been explained at length, there are still folks who view themselves as being part of our team, and yet cling to demonstrably false notions about things like the laws that apply to birth certificates in general, and in Hawaii specifically. That is largely due to a steady stream of incompetence that continues to flow from one who some still regard as possessing any knowledge of the law and legal procedure... We have concluded that providing a venue for those who still seem to support the one who is arguably the worst attorney ever, would not only be a disservice to our country, but it could be considered irresponsible, as a gathering of such people might actually constitute a public danger - for anyone who could still be supporting such an aberration cannot be believed to be mentally or emotionally stable."
Eh, that's okay. She already hates him. I wonder if the birthers who already signed up will get a refund.
