Mike Huckabee, whose win in the Iowa caucuses in 2008 put him on the national political map, holds an early lead there if he were to run again in 2016, according to a new poll. The WPA Research poll shows the former Arkansas governor on top of a field of potential candidates at 14 percent. Sen. Rand Paul (R-Ky.) is in second place at 10 percent, while the rest are in single digits.
