I don’t think the Moneychanger claim works for Obama, for he is not a merchant selling his war sin the Temple of God, but a Political leader. This is more akin to Jesus saying to Render unto Caesar that which is Caesars, and unto God the things which are God’s rather than the episode when Jesus ran the Moneychangers form the Temple.
The analogy doesn’t work since the Government has the right to Tax us. We may disagree on Tax Policy, but its not he same.
That said, I also don’t think Obama is the Book of Revelation come to fruition, I think he’s just a bad President.
