Jim McTague of Barron’s takes a look at who might run Treasury in a new administration:
I believe… that McCain would go for Peter Wallison, a former Treasury official now at the American Enterprise Institute. Wallison for many years had been a leading critic of mortgage giants Fannie Mae and Freddie Mac, predicting that they would eventually collapse, at great cost to the American taxpayer. He gained prominence attacking Congress for the mortgage entities they had created. That earned him some enemies on the Hill and would likely result in a heated confirmation. But few people understand financial institutions better than Wallison…”
I’m biased since Peter’s a colleague but this would be an inspired pick.
