Former president George W. Bush said in an interview airing Sunday that he thinks the odds that his brother Jeb Bush runs for president in 2016 are 50-50

“I think it’s 50-50," George Bush said on CBS's "Face the Nation," according to the Associated Press.

Members of the Bush family have often been asked whether they think the former Florida governor will run. Texas land commissioner-elect George P. Bush (R), Jeb's son, recently said he expected his dad to give it serious thought.

His uncle George W. Bush emphasized Sunday that he doesn't have special knowledge about what's going through Jeb's mind.

"He and I are very close," the former president said. "On the other hand, he's not here knocking on my door, you know, agonizing about the decision. He knows exactly, you know, the ramifications on family, for example. He's seen his dad and his brother go through the presidency. I would give it — I'd give it a tossup."
