Next week on the Exchange, we kick off the new year with a favorite from our archive vault as we talk with author Charles Mann on his book 1493. Then our Issue Tuesday's series continues with a look at where the GOP candidates stand on fiscal policy and such issues as taxation, entitlement spending, and the national debt. We follow up on the results of the Iowa caucus and what they might mean for the New Hampshire Primary, and we get an update and outlook on the Granite State’s economy.
