Is the U.S. currently facing the Bush caused deficit or Obama caused deficit?

The facts are simple, Bush was a disaster in his last term and Obama has just continued on with the same tactics. It took Bush several years to bring the national debt to where it was when Obama took office but now Obama has driven it to the highest in history in just a few short months. We need to stop looking to blame the past administration and look to see what the current one is doing about it, and from where I sit all I see is more debt and more unneeded taxes. I along with many others believed Obama would make change but I didn't believe it would be this bad, I so wish that he was what we were led to believe but he is just like all the rest, a puppet
