President Obama, Sarah Palin, and Rush Limbaugh.

Political opponents? Yes.

Strong personalities? Definitely.

Relatives? You betcha.

Something must run in the family.

The latest discovery from Ancestry.com shows that President Obama is related to conservative radio host Rush Limbaugh, one of his most vocal critics, as well as to frequent political opponent Sarah Palin.

Obama and Palin are 10th cousins, connected through their common ancestor John Smith. Obama and Limbaugh are 10th cousins, once removed, through common ancestor Richard Terrell.

Other political adversaries also share family ties - the study also found that Sen. Harry Reid, the Democratic majority leader in the Senate, is also related to Palin - as well as to conservative commentator Ann Coulter. All three are related through John Lathrop, who was exiled in 1634 to colonial Massachusetts after becoming a minister of an illegal independent church in England.

And a leadership gene clearly runs through Samuel Hinckley's family, because Obama, Palin, and former president George W. Bush are all related through common ancestor Hinckley, who was among the first wave of settlers in America in the 1600s. Obama and Bush are 11th cousins; Palin and Bush are 11th cousins as well.

Obama famously joked about his distant relation to former vice president Dick Cheney back in 2007, after it was revealed that the presidential candidate and the former vice president were 8th cousins. Obama said he was "okay" with the family connection, but he didn't "want to be invited to the family hunting party."

Whether or not Obama, Palin, and Limbaugh and Bush will be gathering for a family barbeque anytime soon remains to be seen.
