This part of Daniel is a bit more specific. It says that the AntiChrist will come from the people who participated in the sack of Jerusalem. Since we're talking about the Roman army, we would have to include Rome and any of its territories.
Dan 9: 26 After the sixty-two 'sevens,' the Anointed One will be cut off and will have nothing. The people of the ruler who will come will destroy the city and the sanctuary. The end will come like a flood: War will continue until the end, and desolations have been decreed. 27 He will confirm a covenant with many for one 'seven.' In the middle of the 'seven' he will put an end to sacrifice and offering. And on a wing of the temple he will set up an abomination that causes desolation, until the end that is decreed is poured out on him."
FWIW, I've always viewed the 'little horn' as a person based on Dan 7 where it was clearly so.
Da 7:8 - "While I was thinking about the horns, there before me was another horn, a little one, which came up among them; and three of the first horns were uprooted before it. This horn had eyes like the eyes of a man and a mouth that spoke boastfully.
The horns represent the kings, their lines, and their kingdoms (as seen when the same symbol is used in chapter 8.
Still wouldn't fit Obama though--the guy is pretty darn tall. :^)
