FRANKFORT, Ky. (AP) — Self-styled Washington outsider Rand Paul dropped his struggling Republican campaign for president Wednesday and is returning to the Senate to run for re-election.

Vowing to continue his drive for less-intrusive government and more restrained foreign policy, Paul, low on support and cash, said he looks forward to earning another Senate term representing Kentucky.

“I don’t really have an absolute answer for what went on with the election and why people make their choices,” Paul said in a telephone interview with The Associated Press Wednesday after a disappointing fifth-place finish in Iowa. “But I do think our voice was an important one and I think as people look backwards they are going to say they were happy to have my voice in the debate.”

 Asked whether he intends to endorse another candidate for president, Paul, a 53-year-old ophthalmologist, replied: “No.”
