although i differ, for the sake of argument, 4 Trillion, 5 Trillion does it really make a difference? it's still unacceptable to me and most rational Americans.
the fact is Obama added more to the national debt in less than 4 years than bush did in 8 years. that's horrible.
it was the regulations that made banks loan to people who couldn't afford their loan. Dodd frank told banks to make those loans. look it up. banks didn't want to make loans without at least 20% down. govt forced them to do it through regulations. so intern the banks sold the mortgages because they knew they'd all default.
GWB increased the deficit from 5T to 12T with his supply side tax cuts that created ZERO net jobs but they did help to make the fake housing market boom worst than it had to be from speculators from the upper tax brackets.
only 1T of the 6T increase under Obama is from actual spending via legislation. and if you don't understand the difference from reduced tax receipts as another negative effect of the recession vs actual spending then you are pretty much a rock and shouldn't really try to understand anything when it comes to econ.
I don't remember anybody from the right being so bent out of shape when Bush blew up the deficit from his legislation that was passed via reconciliation just like Obamacare was.
