No, I think he reserves that finger gesture for certain times. If he did it all of the time, it would be different. Of course, you would expect one of his handlers to point it out if it was just some sort of nervous habit. Pretty sure he has done it just a few times.
BTW, how are you, my FRiend? I remember you from our gatherings in 2000. “Get out of Cheney’s House!” I sat across from you at dinner at that Italian restaurant the night before Bush’s first inauguration.
Just fine my dear FReeper FRiend! We Freeped at quite a few things together during those days. Did we ever think things could come to the state it is now? Sigh.
I googled “Obama - finger” and got a lot of sites with pictures and comments. Of course it would not be covered by the MSM. Another sigh!
FReep on!
