Likely GOP presidential candidate Ron Paul is in Nevada on Thursday as he continues his tour of key early caucus states.

Paul, a congressman from Texas, was in Iowa this week to launch his presidential exploratory committee. He will hold a book signing Thursday and deliver a speech Friday in Nevada, where he finished a distant second in the 2008 presidential caucuses.

The libertarian conservative will also headline a fundraising breakfast for the Washoe County GOP on Friday, according to his exploratory committee.

Paul, who appears all but certain to enter the race, said he will make a final decision next month.

"I will be very surprised if we don't make that decision one way or the other by the middle of May," he said of his final decision on Tuesday, when he announced his exploratory committee.
