Cars, Contraception and Calling China on the iPhone

We discuss Mitt Romney's tenuous grip on Republican front-runner status, GM's record profits, JP Morgan CEO Jamie Dimon's call for higher taxes on the very rich and what lessons to take from The Fear Index, a new novel set in a future where robots have displaced humans on the assembly line...and in the boardroom. Joining us this week as guest panelists are Matthew Continetti (Washington Free Beacon) and Chrystia Freeland (Thomson Reuters Digital).
