This week on The Ticket 2016: There's less than a month to go until the Iowa caucuses, and we have a new frontrunner. Texas Sen. Ted Cruz has taken the spotlight after recent polls show him jumping ahead of Donald Trump. KUT's Ben Philpott and The Texas Tribune's Jay Root talk with Tribune reporter Patrick Svitek, who's on the road with the Cruzin' to Caucus bus tour.

And with all the current campaign focus on Iowa, Root and Philpott attempt to explain how the Hawkeye State gained its prominent role in primary politics.
