A longshot Republican Senate candidate in New Jersey is banking his campaign on massive changes to the Federal Reserve.

Jeff Bell, who is running against incumbent Democrat Sen. Cory Booker, is making criticism of the Fed and a return to the gold standard the centerpiece of his campaign.

A 70-year-old former aide to Presidents Richard Nixon and Ronald Reagan and Rep. Jack Kemp, Bell has lived outside New Jersey for three decades. He faces Booker, the popular former mayor of Newark who is fresh off a 2013 special election win, in a blue state where it's expensive to advertise.
