2010 U.S. Senate election
Grayson ran in the 2010 Republican primary for
U.S. Senate in
Kentucky, losing to
Rand Paul by a 23-point margin.
Endorsements Grayson was endorsed by Senator
Mitch McConnell, former Vice President
Dick Cheney, former New York City mayor
Rudy Giuliani, Senator
Rick Santorum, Representative
Hal Rogers, and several members of Kentucky's State legislature. In late April,
Focus on the Family founder
James Dobson endorsed Grayson, saying he was the only candidate with the conviction to lead Kentucky. But a week later, Dobson rescinded his endorsement and endorsed Paul, claiming to have been misled by senior Republican officials about Paul's stance on abortion. Dobson did not claim Grayson was complicit in misleading him, but two days later Paul aired commercials claiming that Grayson and other GOP leaders "deliberately deceived one of America's leading conservatives, Dr. James Dobson." The ads were later removed.
Results Grayson lost to Paul by a 23.33% margin, with 124,710 votes to Paul's 206,812. After conceding the election to Paul, Grayson said, "It's time to put all differences aside, unite behind Dr. Paul. He needs our help and I for one stand ready to serve". He downplayed the effect of the Tea Party's support for Paul, saying, "I think there are just so many things at work here, it's hard to pinpoint it. I think the tea party [vs.] conservative establishment thing is a little too simplistic." ==Later career==
