Borrowing a page from his father’s playbook, Republican Senate candidate Rand Paul of Kentucky raked in more than $430,000 during a recent Internet-based fundraising drive.

Paul, a Bowling Green eye surgeon, is the son of Texas Rep. Ron Paul, who gained attention in 2008 by running for the Republican presidential nomination on a libertarian platform.

The online fundraising event, which coincided with the elder Paul’s 74th birthday, attempted to mimic his father’s successful “money bomb” efforts in 2008 that attracted small donations from conservatives nationwide, including $6 million in a single day.

Paul announced his Senate bid earlier this month, soon after Republican Sen. Jim Bunning, a Hall of Fame major league baseball pitcher, announced his decision to not seek a third term in 2010.
