Sarah Palin says that McCain sounded the alarm on Fannie Mae and Freddie Mac two years ago. Our colleagues at PolitiFact questioned that claim, calling it “barely true.” Palin’s referring to a bill that would have increased oversight on Fannie and Freddie. McCain signed onto that bill as a cosponsor, but PolitiFact says it wouldn’t have lessened the current economic crisis. And in our recent article about assigning blame for the economic crisis, we add that by the time McCain added his name to the bill, the crisis was well underway. Home prices began falling only two months later.
