Donald Trump retakes the lead in Iowa, with a mere seven days to go. Two pianos drop on Ted Cruz this week, with Sarah Palin endorsing Trump and Iowa Governor Branstad slamming Cruz. How will Cruz supporters take these new developments? Will Glenn Beck's endorsement help or hurt the Cruz campaign? Meanwhile, National Review devotes a full issue to blasting Trump as an unmoored "populist." Would NR founder William F. Buckley agree? Is Trump a conservative or not? We argue "yes" he is -- as we review the history of "conservatism" itself. Might National Review's attempted purge of Trump backfire? How have conservative intellectuals managed to lose touch with their base? We suggest that uncontrolled immigration is an "existential" threat to America, and that Establishment inaction on the issue has become the "deal-breaker" for voters in 2016. Plus, we consider the possibility that Trump could be a "race healer" in America, as he is endorsed this week by both Willie Robertson of Duck Dynasty and Chingy -- the hip/hop rapper. Also, we celebrate today's Denver Broncos' victory and get worked up about the upcoming Super Bowl. Go Peyton!! With raucous music and listener calls.
