The candidates who dropped out were U.S. Sen. Rand Paul (R-Ky.), former U.S. Sen. Rick Santorum, former Arkansas Gov. Mike Huckabee and former Maryland Gov. Martin O’Malley.
On Wednesday, after Politico reported Paul was dropping out of the race, he affirmed his exit in a video he posted on Twitter.
“I think the idea of liberty lives on in you and us,” Paul says in the video. “We will continue to fight. Tonight is the beginning. Liberty will fight on. We fight on.”
Paul, who seemed to be making swan song at a rally on the day of the Iowa caucuses, obtained 4.5 percent of the vote in the GOP caucuses.
Later on Wednesday, CNN reported Santorum would join Paul in exiting despite the former senator’s declaration he would continue to campaign in South Carolina. Santorum won 1 percent of the vote in the GOP Iowa caucuses.
Those announcements follow declarations from Huckabee and O’Malley on the night of the caucuses they were leaving the race.
Huckabee, who vote 1.8 percent of the vote, declared Monday on Twitter with no fanfare his intention to suspend his campaign.
I am officially suspending my campaign. Thank you for all your loyal support. #ImWithHucK

Multiple media outlets on Monday reported O’Malley, who won 0.6 percent of the vote in the Democratic caucus, would suspend his campaign.
The exit of both Huckabee and Santorum after Iowa is noteworthy because Huckabee won the GOP caucuses in 2008 and Santorum narrowly won in 2012.
