Republican Rand Paul Ends his Presidential Campaign

Presidential hopeful Rand Paul announced two days after the Iowa Caucus that he will be ending his campaign.

"It's been an incredible honor to run a principled campaign for the White House," the Senator of Kentucky said in a statement. "Today, I will end where I began, ready and willing to fight for the cause of liberty."

A source with knowledge of Paul's campaign in New Hampshire added to ABC News, "Obviously people here at the office are disappointed, but we think his message will continue to resonate with the freedom movement in the Republican Party."

In Monday's caucuses, Paul finished fifth with 4.5 percent behind his opponents, Ted Cruz, who won, Donald Trump, Marco Rubio and Ben Carson.

Throughout his campaign, which was announced on April 7, 2015, Paul has been focused on reducing the nation's influence on a domestic and international level with the objective of defending liberty. Paul's campaign failed to gain momentum on a national level and his poll numbers never passed the single digits.

Paul also had a difficult time convincing his father's supporters. Pauls' father, Ron Paul, ran for president in 2008 and 2012. He was also a former Texas congressman.

Drew Ivers, the elder Paul's 2012 Iowa chairman, explained why the younger Paul was not able to secure enough support.

"His decision to move to the middle and support a number of moderate Republicans in the 2014 elections, that sent us a real signal about the application of his ideology," said Ivers, who did not endorse Rand Paul, said reported by the Washington Post. "He muddled on his message, tried to get the left, and I told him it would backfire. ... I just saw someone trying to do too much and be too many things to too many people. His name is Paul, I told him. You can't defy gravity,"

Paul will now focus on his re-election campaign in Kentucky. He will be facing democrat Jim Gray, who is the mayor of Lexington.
