Believe it or not, that is a really good question, and
a deeper one than you realize. That is a question that
gets asked a lot, I have no idea how many books have been
written on the subject, and I will honestly be willing
to talk about it.

Fact of the matter is, God is not a slot-machine, He is
not manipulated by us though we may think we can, and
His plan for life and the world is beyond our comprehension.
"My thoughts are not your thoughts" He says in scripture.
So while many people were praying, the Lord does as He
sees fit, because He sees outside of time,He sees the
bigger picture. Did Obama win because God endorses him,
or is Obama the punishment we get for not doing what we
should? I don't know. I doubt either, actually. You are
forgetting freewill. God allows us to act rightly or wrongly,
and He wants us to choose the right without being forced
or rewarded like trained dogs. Whatever happens from this
point on will be the result of that freewill. I can pray
for an outcome of anything, but sometimes the answer is
"no" or "not now" or

"keeping praying" or "trust Me." God's plans are bigger
than mine or yours, and He will accomplish those plans
no matter what.

I know however that His plans are are
not designed to hurt me, but to prosper and grow me because
He loves me, and ultimately will welcome me home to be
with Him for eternity.
