"How will the Presidential candidates impact the housing crisis?"
They won't.
"How have you been impacted by political decisions in regards to your housing situation?"
Can't really say I have been. I lost a lot of value in my home when the bubble burst, but I knew all along that my home was overvalued. The value corrected itself and now I'm pretty much right where I should be. I blame uneducated homebuyers who are incapable of assigning proper valuation to a property or acknowledging their financial limitations, and unethical real estate/ mortgage "professionals" for the bubble more than I blame politicians.
The government can pass a law stating it's legal to give a loaded shotgun to a retarded chimpanzee and then send that chimp into a crowded mall but that doesn't mean it's a good idea. Everyone should have seen that that chimp was going to shoot up the housing market.
