Greg Corombos of Radio America and Jim Geraghty of National Review react to terrible Iowa poll numbers for Chris Christie and other news that suggests Jeb Bush is snagging major donors in Christie’s backyard. They also discuss the GOP’s oddly weak ability to handle questions about childhood vaccinations and media drooling for the chance to brand Republicans as anti-vaccine wackos. And they react to a slim plurality of Iowa GOP voters agreeing with Mike Huckabee that Beyonce’s music constitutes “mental poison.”
