Is this for real? I'm skeptical.
If you send thousands of Obama supports out to meet the public how could you not get this kind of response occasionally.
Possible, yes. Propable, no.
Speaking anecdotally of course, as a white male, I've spent my 50 years, mostly, in Illinois and Indiana. The term, "darky," pre-dates even me.
So I think, (or, at least, would like to think), that an older man would be a little more composed that to utter a line like that.
Also, the term, "hang," is a bit suspicious because an expletive is so much more plausible in a fit of pique.
Just my opinion, of course. I said I was skeptical; I called no one a liar. (I thought it, though).
Regards.
