First off the Anti-Christ is empowered before we're gone. Otherwise we wouldn't have been warned about him.
Secondly, none of what you described fits Obama.
Lastly, 88.46% of the people agree that Obama is not the Anti-Christ. Those are quite overwhelming numbers.
First off:
Who are the "heaven-dwellers" that praise God that "salvation" (immortality when Christ appears) "has now come" when the devil is cast down to the earth before the "mouth" is empowered and who the "mouth" - ANTICHRIST - blasphemes?
Rev 12:9 And the great dragon was cast out, that old serpent, called the Devil, and Satan, which deceiveth the whole world: he was cast out into the earth, and his angels were cast out with him.
10 And I heard
a loud voice saying in heaven, Now is come salvation, and strength, and the kingdom of our God, and the power of his Christ: for the accuser of
our brethren is cast down, which accused them before our God day and night.
11 And
they overcame him by the blood of the Lamb, and by the word of their testimony; and they loved not their lives unto the death.
12
Therefore rejoice, ye heavens, and ye that dwell in them. Woe to the inhabiters of the earth and of the sea! for the devil is come down unto you, having great wrath, because he knoweth that he hath but a short time.
13 And when the dragon saw that he was cast unto the earth, he persecuted the woman which brought forth the man child.
14 And to the woman were given two wings of a great eagle, that she might fly into the wilderness, into her place, where she is nourished for a time, and times, and half a time, from the face of the serpent.
15 And the serpent cast out of his mouth water as a flood after the woman, that he might cause her to be carried away of the flood.
16 And the earth helped the woman, and the earth opened her mouth, and swallowed up the flood which the dragon cast out of his mouth.
17 And the dragon was wroth with the woman, and went to make war with the remnant of her seed, which keep the commandments of God, and have the testimony of Jesus Christ.
And I stood upon the sand of the sea, and saw a beast rise up out of the sea, having seven heads and ten horns, and upon his horns ten crowns, and upon his heads the name of blasphemy. 2 And the beast which I saw was like unto a leopard, and his feet were as the feet of a bear, and his mouth as the mouth of a lion: and the dragon gave him his power, and his seat, and great authority.
3 And I saw one of his heads as it were wounded to death; and his deadly wound was healed: and all the world wondered after the beast.
4 And they worshipped the dragon which gave power unto the beast: and they worshipped the beast, saying, Who is like unto the beast? who is able to make war with him?
5 And there was given unto him a mouth speaking great things and blasphemies; and power was given unto him to continue forty and two months.
6 And
he opened his mouth in blasphemy against God, to blaspheme his name, and his tabernacle, and them that dwell in heaven.
7 And it was given unto him to make war with the saints, and to overcome them: and power was given him over all kindreds, and tongues, and nations.
Did you catch the order of events there?
1. Devil is cast down when the church is caught up.
2. Devil sends flood (armies) against Israel.
3. Devil empowers antichrist ("mouth") which then blasphemes the heaven-dwelling church - "overcomers by the blood of the Lamb" whose "salvation" (immortality when Christ appears in the air) "has now come".
4. Makes war with those who choose to believe after we're gone.
