A woman in a hot air balloon realized she was lost.
She lowered her altitude and spotted a man in a boat below.
She shouted to him:

"Excuse me, can you help me? I promised a friend I
would meet him an hour ago, but I don't know where I am."

The man consulted his portable GPS and replied,
"You're in a hot air balloon, approximately 30 feet above ground
elevation of 2,346 feet above sea level. You are at
31 degrees, 14.97 minutes north latitude
and
100 degrees, 49.09 minutes west longitude.

She rolled her eyes and said, "You must be an Obama Democrat.

"I am," replied the man. "How did you know?"

"Well," answered the balloonist, "everything you told me is technically
correct, but I have no idea what to do with your information,
and I'm still lost.  Frankly, you've not been much help to me."

The man smiled and responded, "You must be a Republican."

"I am," replied the balloonist. "How did you know?"

"Well," said the man, "you don't know where you are --
or where you are going. You've risen to where you are,
due to a large quantity of hot air. You made a promise and you
have no idea how to keep it, and you expect me to solve your
problem.   You're in exactly the same position you were in
before we met, but somehow, now it's my fault."
