Iraq
Whoever said Bush and the Republicans weren't responsible for Iraq? Bush overthrew the dictor Saddam, much to your disgust. I give him all the credit in the world for that. Personally I don't agree with the way he conducted that war, but I still give him the credit/responsibility of it.
The Iraq war was illegal and immoral. It had more in common with Nazi Germany, than it did with the principles this country was founded upon. Do you not know how wrong it is to attack someone, that did not attack you first? And it is not up to us to decide who can (and cannot) be the leader of a sovereign nation.
We spent over $4 trillion US taxpayers dollars on that war and what did we get in return? Nothing! ******* nothing! If you wanna talk about unecessary government spending, that's a good place to start.
the debt
The trillions in debt is due to both parties. Yes, Bush ran it up...so much he turned off conservatives and thats why Repubs lost the house in 2006. But since Dems have been in power since 2006, they've only made it worse. So I'm not sure what your point here is...if it's a bad thing then why do you want the current Congress to borrow another trillion to pay for ObamaCare? The only party showing any interest in reducing debt are Republicans....the Tea Party element at that.
Bullshit! Anyone serious about cutting the deficit, would start by cutting the defense budget. And no republican is willing to do that.
The Bush Tax Cuts
I have no problem giving Bush credit/responsiblity for his "tax cuts". Obama and the fully controlled Dem Congress extended those same "tax cuts", although at that point they were simply the permenant tax rate for nearly 10 years. So if you have a problem with the current tax rates (e.g."Bush Tax Cuts"), then take it up with Obama and Reid.
The tax cuts reduced government revenue and contributed to the deficit we're facing now.
The economic meltdown
The Housing bubble is what caused the economic meltdown. Banks giving out loans to people for houses prices way over what they should of been worth. Also, giving out loans to people with bad credit, but that was largely because liberal enacted policies forced such banks to give loans to poor people...mainly blacks. Then of course there is Fannie Mae and Freddy Mac, (D)-bag controlled agencies that refused to acknowledge the oncoming crisis, and just continued to force banks to give loans to "low income" families.
Wrong! De-regulation caused the meltdown. The derrivitives market ballooned to over 180 times the collective GNP of all the nations on the planet. The housing bubble never had numbers that high.
And the government did not tell banks to relax standard loan reviewing procedures, when vetting the credit worthiness of applicants. BTW, most of the defaulted loans were from private lenders.
