It's why Lance Armstrong wasn't nominated either
Fox News All Star Fred Barnes explains the selection of Ben Bernanke to succeed Alan Greenspan for Wall Street Journal (subs. req'd) readers:
Since the White House views the Fed staff as unfriendly to President Bush's fiscal policy, that ruled out Mr. Kohn [Bernanke rival]. He also is an environmentalist who rides a bike to work, thus not a Bush type of guy.
UPDATE: Aside from the War on Bikers, Brad DeLong finds that Barnes is peddling total shite on Bernanke's economics as well.
