Harrison Lavelle and Armin Thomas sit down with Lincoln Davis (D), former Representative from Tennessee's 4th Congressional District. Davis served in the Tennessee legislature from 1980-2002 and in Congress from 2003 to 2011. Davis discusses his tenure in public office, the decline of rural Democrats and the Blue Dog Caucus, and the rise of Tea Party Republicans - as well as his own experience as a victim of a voter purge.
