“It hasn’t been polled very much. So I think it’s very uncertain who’s going to win,” he told CNN on Saturday. “I’m not going to endorse anybody in the race.”
“I’ll probably keep that private,” he added when asked whom he vote for.
Paul convinced party leaders to switch Kentucky from a primary to a caucus state so he could run for president and Senate simultaneously this year.
Paul repeatedly clashed with Rubio during the campaign over foreign policy. Paul argued that the United States had overextended its military in the past decade, while Rubio positioned himself as one of the more hawkish candidates.
Paul also battled with Cruz over libertarian voters. Tensions built between the two campaigns as Cruz swiped activists who had supported Paul’s father Ron Paul’s past presidential campaigns.
In January, Paul said the prospect of front-runner Trump becoming the party’s nominee was more worrisome because of his broad view of executive authority.
“I do worry a little bit more about Donald Trump,” he said at the time. “The main reason I do is that I believe he wants more power to come to him and ‘he’ll take care of us all’ if we just give him more power, but I’m from a limited government tradition.”
