I don't know what one of those is. I tried looking it up, but after the 5th or 6th embittered American right-wing website I had to give up in confusion ...
You only seem to come across the term on those kinds of site, and it always seems to be a term of abuse: it seems that apparently nice Mr Obama is really Che Guevara, Hugo Chavez and fidel Castro all rolled into one, plus influences of Idi Amin and some of the worst traits of Benito Mussolini. Gosh! who'd have thought it?
I certainly wouldn't want anyone like that to be my president. Tell me, how do you think he hoodwinked the Democrat Party into thinking he was one of them? Do you think he misrepresented himself, perhaps?
