U.S. Rep. Ron Paul, a Republican presidential candidate and father of Bowling Green opthamologist Rand Paul, will speak at Bowling Green High School at 2 p.m. Friday, four days before Kentucky’s primary election.

Ron Paul, 71, has been elected to Congress 10 times from Texas. In 1988 he was the Libertarian Party’s nominee for president, receiving less than one-half of 1 percent of the vote.

In this year’s presidential campaign, numerous polls showed Paul’s support hovering in single digits, but he set online fundraising records and argued that polls didn’t reflect his true level of support. Most of those postulated Paul backers never showed up on election day, winning him only 19 delegates out of nearly 2,000.

Nevertheless, he has kept on stumping, and his backers are reported to be organizing a public protest at the Republican National Convention in September. His book “The Revolution: A Manifesto” is at the top of the New York Times nonfiction bestseller list.

“Ron Paul has never voted for a congressional pay raise, never taken a congressional junket, never voted for a tax increase, and never voted for an unbalanced budget,” says a press release from his family and local campaign. “Ron Paul returns money from his congressional budget to the U.S. Treasury each year.”

He remains on the Kentucky primary ballot for May 20, along with John McCain, Mitt Romney, Alan Keyes, Mike Huckabee and Rudy Giuliani, though all those other candidates except for McCain, the party’s prospective nominee, have ended or suspended their campaigns.
