Raleigh-based Republican consultant Carter Wrenn has had a front-row seat to decades of political history. He’s worked for the campaigns of U.S. Sen. Jesse Helms and Ronald Reagan starting in the 1970s.

He’s now written a book on his experience that offers an inside look at some key moments and controversial figures in politics. He spoke with WUNC's Colin Campbell about the book, “The Trail of the Serpent: Stories from the Smoke-Filled Rooms of Politics,” and on some aspects of his political work that he’s come to regret.
