We’ll talk about last night’s victories by former Massachusetts Gov. Mitt Romney in the Republican primaries in his home state of Michigan and Arizona.

Rick Santorum, former House Speaker Newt Gingrich and Congressman Ron Paul? In this hour of Radio Times, Marty welcomes back to the WHYY studio Republican media strategist CHRIS MOTTOLA and Democratic media strategist NEIL OXMAN.
