Did Jeb separate himself enough from Bush family policies?

Former Florida Gov. Jeb Bush did "not really" sufficiently prove he could stand on his own as a 2016 presidential candidate in a speech at the Chicago Council on Global Affairs, said CBS News congressional correspondent Nancy Cordes.

"He needs to show he's his own man. You can't become president if people don't see that you have your own distinct identity," Cordes said Thursday on "CBS This Morning."

During the event Wednesday, Bush offered areas where his foreign policy strategies would be different from those of his brother George W. Bush and father, George H.W. Bush. While he did comment on his brother's handling of the Iraq War, citing failed actions to secure Baghdad after the invasion, Bush's discourse was not enough to dispel critics.

"Even President George W. Bush has said that; so that's not a big revelation," Cordes said. "It shows this is going to be a very slow, very delicate process. Because he doesn't want to look like he's being disloyal to his family either."

Along with criticizing President Barack Obama's strategy to combat the Islamic State of Iraq and Syria (ISIS), Bush may need to go another step further to prove his independent thinking on foreign policy. At the moment, his "preliminary and informal" group of advisors includes George H. W. Bush's secretary of state James Baker and the second homeland security secretary under George W. Bush, Michael Chertoff.

"They are all, or almost all, either George W. Bush or George H.W. Bush's advisers, which I think shows that his foreign policy views really do lie somewhere between his father and his brother," Cordes said. "Though in fairness, it would be very difficult to craft a team of foreign policy advisers who didn't work for either of the last two campaigns and administrations on the Republican side."

Bush's family, of course, is an impossible to ignore piece of the puzzle. With 12 years between the two former presidents, their influence is likely to serve the former governor well.

"He's got that early-name recognition; he's got tons of donors who are ready to give him money," Cordes said.

Not everyone in the Bush family has always been entirely supportive though. After initially saying in 2013 there were "enough Bushes," his mother Barbara had a change of heart at a family literacy foundation diner last Friday.

But the 180 degree change of mind wasn't enough for comedian Conan O'Brien to ignore. Thursday night following Bush's speech he said: "Barbara Bush, has given her son her blessing to run for President. So now Jeb's campaign slogan is, 'My Mommy Said I Could.'"

"You hope that your whole family is going to be on board when you decide to run for president. And she's now says that she is. But those video tapes are there, those clips are there and opponents are going to bring it up," Cordes said.

With less than a year remaining before initial 2016 contests, those opponents may not be that far behind. Nearly half the self-identified Republicans in a recent CBS News poll said at this point they would consider voting for Bush, but Former Arkansas Gov. Mike Huckabee took a close second at 46 percent.
