Crazy people do irrational things. This guy is nuttier than a Stuckey's Pecan Log. Their attention span for some things is short, and they persevorate on others.
The guy went to an Obama rally, falls in love with Obama and makes a donation. Nothing else catches his attention the next day, so he still loves Obama and makes another donation.
On the third day, maybe Nickelodeon was playing a Ren and Stimpy marathon that captured his attention and Obama was forgotten. Or maybe with his newfound love for Obama, the nut goes on the net to learn more about him, his religious affiliations and mentors. That sucks him in for months, or whatever length of time, and he decides to go the Jeremiah Wright route and make his own hate videos.
Crazy people are unpredictable and it's difficult to figure out rationale for their actions
Or maybe he was given money by Soros handlers and donated to BO's campaign in his name.
Ah, yes--the infamous Stuckey's Pecan Log.
The only foodstuff that looks the same going in as when it comes out......
