Sen. Jim DeMint (R-S.C.) gets all the attention for backing underdogs, but Mike Huckabee is getting in on the action too.

DeMint will get plenty of play tonight – good or bad – for endorsing Marlin Stutzman in today’s Indiana GOP Senate primary. But Huckabee has also endorsed the conservative state senator over the establishment favorite, former U.S. Sen. Dan Coats (R-Ind.). And, in fact, Huckabee has endorsed many of the same candidates DeMint has thus far, albeit after DeMint set the standard.

DeMint backed Marco Rubio mid-June 2009, but Huckabee was also one of the first national political figures on board. He endorsed Rubio a week later.

DeMint endorsed Chuck DeVore in the California Senate race in November and Stutzman two weeks ago. Huckabee followed by endorsing both men last week.

Huckabee took to last week to explain why he is backing the three candidates, two of which – DeVore and Stutzman – remain decided underdogs.

“We need three firm votes in the Senate AGAINST bailouts, Obamacare and the many tax increases that our coming our way to pay for both,” Huckabee wrote. “We need strong defenders of the 2nd amendment, life, traditional marriage and wait for it … REAL BORDER SECURITY!”

Big-time Senate candidates aren’t the only underdogs Huckabee is backing. He has also endorsed businessman Les Phillip in the race against Rep. Parker Griffith (R-Ala.). And in his home state, he’s backing restaurant owner Scott Wallace in a primary with former U.S. Attorney Tim Griffin, a top recruit of the National Republican Congressional Committee (NRCC).
