Well, the SEC under Bush, allowed the Banks and other Wall Street investors to "invest" in high-risk mortgage securities.The answer to lower any further risk of that happening was the Dodd-Frank bill, which was watered down by the Republican congress, and is and has been on the Republican radar to eliminate. So, if that eliminates the solution to the problem, there is a good chance that another mortgage crisis could occur.......stand by for more action by the Republicans to screw things up again....last time the Republicans had majorities in both the House and the Senate and held the White House was just before the Great Depression.....
