Mike Huckabee, who was governor of Arkansas from 1996 to 2007, suspended his second presidential campaign on February 2, 2016.
During his 2008 run, the former pastor was the surprise winner of the Iowa caucuses and went on to carry several other states, showing particular appeal to more religious Republicans.
Huckabee eventually was defeated by John McCain, who had more support from the GOP establishment and more moderate and secular GOP voters. The former governor then spent the next several years hosting a television show on Fox News.
For his second run, Huckabee tried to build the same kind of following among grassroots Republicans and religious voters. Yet Huckabee was not able to resonate among moderate Republicans or evangelical conservatives, who have been leaning more towards Donald Trump and Sen. Ted Cruz.
A few big donors funded a super-PAC to support Huckabee's campaign. But similar to 2008, he almost ran out of money for his campaign, finishing with only $133,244 cash on hand.
Secretary of State Bill Gardner predicts that there will be a total of about 550,000 votes cast on Tuesday - more than the 529,000 cast in 2008.
