Quoting above:

There have been many people throughout history (Hitler, Nero, Napoleon) that could have been ascribe as the A/C simply because we the people made scripture fit the person we wanted it too.

In this sense there were many other anti-Christs throughout time, but the Bible specifically warns each of us to be watching for as it relates to end time events.

God's word is very specific, no one will know who the actual A/C is until his appointed time, which God provided us with two important clues should we miss the first one.

Daniel 9:27 and Mark 13:14, God allows us to know this ahead of time so that those who are faithful and watching the signs will know without a doubt who the real A/C is.

I don't about Obama or anyone else at this time, nor does anyone know his identity at this point in time, it all speculation as to who he is, but through God word we can eliminate who the A/C isn't, and he isn't the POPE!

Praise God!
