The former New York City mayor who had a memorable dust-up with Ron Paul during the 2008 Republican presidential debates today endorsed against his son in Kentucky’s GOP primary for U.S. Senate. Giualini threw his support behind Kentucky Secretary of State Trey Grayson, who is currently trailing Rand Paul in the contest to replace retiring Sen. Jim Bunning (R-KY).
Paul was recently endorsed by Bunning, Sarah Palin, and Steve Forbes, among others. Prominent Grayson supporters include Dick Cheney, Rick Santorum, and now Rudy Giuliani. The primary is May 18. Both Republicans lead both major Democratic candidates in the public polls.
