Wrong. It was dems along with repubs who allowed this. You're still a delusional hack.
So:
1. You first said it was the fault of Democrats and you made the lying, bullshit claim that Democrats killed GSE reform in 2003,
when it was actually your guy Bush who killed GSE reform.
2. Rather than own up to being wrong, you try to pretend that this was somehow a bi-partisan effort, yet you don't bother to explain how.
3. I can tell you right away that it wasn't the fault of both sides...it was the fault of one side only. Specifically the side that allowed a "dramatic weakening of underwriting standards for subprime loans beginning in early 2004 and extending into 2007". Who imposes those standards? Regulators. And for whom do the regulators work? For the Executive Branch. And who was in charge of the Executive Branch from late 2004 through 2007? Bush the Dumber.
So please explain what Democrats had to do with Bush's regulators ceasing the enforcement of lending standards for subprime loans beginning in late 2004 and extending into 2007? I'll save you the time;
you can't. Because the deregulation that caused the mortgage bubble was entirely, 100% the fault of your shitty laissez-faire conservative shit policies.
Even Bush's Tax Cuts were responsible for the housing bubble, as Bush campaigned in 2004:
Bush Ties Policy to Record Home Ownership
Touting his tax cuts as the economy's savior — and pointing to the strong housing market as proof — Bush said "more people own their own home now than ever." More than 50 percent of minorities owned their own homes in the last three months of 2003 for the first time ever, the president said.
So you got Bush crediting the housing bubble to his tax cuts, you got Bush's regulators backing off the enforcement of standards, and you got Bush's own Working Group in 2008 saying all of that was the cause of the economic turmoil.
But you're gonna somehow work in blame for Democrats because you cannot reconcile the shit you believe sucks and is the cause of most of the issues we face today.
