The highlight of Larry’s popular syndicated radio show tomorrow (broadcast every Saturday from 10 a.m. to 1 p.m. Eastern Time, caught via the local air waves or over the web here) will be his live interview with Rick Santorum, who, along with another stellar line up of guests — including our own Bob Costa, Congresswoman Nan Hayworth, William Isaac (who’ll be talking about the Fed stress test), Steve Weiss, Brian Wesbury, James Pethokoukis, Tony Fratto, and Jennifer Rubin — will be discussing Obama’s terrible energy policy fiasco, the Illinois primary, a stronger U.S. economy and dollar (is it time to sell your gold?), a bullish stock market, and so much more. Listen and take notes — there will be a quiz!
