Well I can see some general patterns, and admit I am only making an educated spiritual guess based on the factors I can see. Both good and evil have momentum. However if they are granted anywhere like an equal footing, good will simply cream evil. What do you expect out of a contest of God vs. Satan? Anyhow, Obama is the result of American lassitude and laxity. God let it be punished, negatively to show that no, that’s not the thing to do, but positively to provide the resistance against which things like the Tea Party get their training. These are general patterns well supported by the bible; I’m not inventing anything new here.
I don’t see good vs evil. I see Godly vs unGodly. Satan is already defeated, he’s just waiting on the execution. But he can wreak havoc in the church until his date, mostly because we keep letting him in the door.
