Some proponents of limited government understandably yearn to see Mitt Romney’s recently announced running mate, Paul Ryan, as something like the pure intellectual descendent of Friedrich Hayek and Milton Friedman. Some on the left, meanwhile, will be tempted to portray him as a heartless monster who only wants to enrich the 1 percent. Paul Ryan the politician is more complex than either portrait. Far from throwing granny under the bus, his efforts at budget reform are an essential step in saving Social Security and Medicare, along with improving the long-term fiscal health of the nation. On the other hand, and although his American Conservative Union score is a solid 91.69, he did vote for TARP, the bank bailout, and the auto bailout–government intrusions he has said he now partially regrets.
