After finishing fifth in the Iowa caucus with less than 5% of the vote, Senator Rand Paul has announced that he is suspending his presidential campaign in order to focus on his Senate campaign in Kentucky.

CNN reports:

“It’s been an incredible honor to run a principled campaign for the White House,” Paul said in the statement. “Today, I will end where I began, ready and willing to fight for the cause of Liberty.”

Paul, a Kentucky Republican, is expected to instead place his focus squarely on his Senate reelection bid, where he faces a wealthy Democrat, Lexington Mayor Jim Gray, who has the money to partially finance his campaign.

Paul finished a disappointing fifth place in Monday’s Iowa caucuses, registering just 4.5% of the vote despite placing a heavy emphasis on the state’s college towns to bring out younger voters inspired by his libertarian-minded message. He promised that night to continue his campaign.

But the Paul sources said a morning-after review made clear to Paul that there was not a viable path to winning the Republican nomination and that fund-raising was becoming extremely difficult.

It’s not clear whom Rand’s supporters will now turn to in the 2016 Republican primary, but it will be interesting to see how that plays out.
