Doesn't matter that Bush requested it. Democrats had the final say and Obama signed it. It's Obama's baby. Obama and the democrats could simply have said "No way are we going to spend that much"
I have a story for you...there was this kid who asked his parents to buy him this $50k car for his 18th birthday. The parents knew it was more than they could afford, but they broke out the credit cards and got a loan and bought it for him anyway. It was a pretty big burden for them.
Now who bought the car, the kid or the parents? Because according to the logic you just posted, you think the kid bought it. Am I right?
