The back and forth between John McCainJohn Sidney McCainLawmakers worry about rise of fake video technology Democrats put Dreamers and their party in danger by playing hardball Trump set a good defense budget, but here is how to make it better MORE and Barack ObamaBarack Hussein ObamaOvernight Energy: Dems ask Pruitt to justify first-class travel | Obama EPA chief says reg rollback won't stand | Ex-adviser expects Trump to eventually rejoin Paris accord Overnight Regulation: Trump to take steps to ban bump stocks | Trump eases rules on insurance sold outside of ObamaCare | FCC to officially rescind net neutrality Thursday | Obama EPA chief: Reg rollback won't stand Ex-US ambassador: Mueller is the one who is tough on Russia MORE over VP vetter Jim Johnson's mortgages is pretty funny — maybe the two candidates could actually trade Charlie Black and Jim Johnson and declare a truce.

But has the McCain campaign noticed the new economic policy adviser just hired? Jason Furman, who at 37 years old is an expert in fiscal policy, has such an impressive resume that you have to wonder if he started college at age 6. Furman has served as staff economist in the White House Council of Economic Advisers under Clinton, was senior director for the National Economic Council, has worked at the World Bank, earned a Ph.D. at Harvard University and was an economic adviser to John Kerry in 2004. And according to the New York Sun Furman is a Wal-Mart defender. In 2005 he published a paper titled "Wal-Mart: A Progressive Success Story," heralding the consumer savings delivered by the chain that is considered a corporate bogeyman to many Democrats.

It should be noted that Obama used the company in one his most aggressive outbursts against Hillary Clinton at a debate early on in the primary season. "While I was working on those streets watching those folks see their jobs shift overseas, you were a corporate lawyer sitting on the board at Wal-Mart," Obama said.

Of course, McCain isn't criticizing Wal-Mart. But he may find this funny.
