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.

Here's the rundown:

1. Huckabee: 14 percent

2. Paul: 10 percent

3. Wisconsin Gov. Scott Walker: 8 percent

4. Rep. Paul Ryan (Wis.): 7 percent

4. Former Florida governor Jeb Bush: 7 percent

4. Sen. Ted Cruz (Tex.): 7 percent

7. New Jersey Gov. Chris Christie: 6 percent

8. Former senator Rick Santorum (Pa.): 5 percent

9. Texas Gov. Rick Perry: 3 percent

9. Sen. Marco Rubio (Fla.): 3 percent

10. Louisiana Gov. Bobby Jindal: 2 percent

10. Someone else: 2 percent

About a quarter of voters -- 26 percent -- said they were undecided.

As with any early poll of a hypothetical field of candidates, this poll should be taken with a grain of salt. But it does suggest that Huckabee is still well-regarded in Iowa, even as other Republicans have emerged as bigger voices in today's GOP.
