It isn’t correct that his surviving children are possible presidents. Neil Bush, Marvin Bush and daughter Dorothy have never, and will never, run for office. Time to get real. They are all getting old themselves and personally desire no political office. Of the grandkids, so far only Jeb’s son George P wants to run for office. He’s expected to do so in TX but don’t yet know for which one.
No one was advocating that any of them would actually ever run for president, exactly. Unless you are a Bush family member using words such as never, really are not correct either.
