Actually, there should be residual RNA simularities, (from several thousand generations back), that I believe will justify the "1."
It's unfortunate that anyone has to share a genetic branch with Chimpy, but that's evolution for you!
I'll bet Jeb wishes he didn't share dna with chimpy.
Truer words have never been spoken.
I believe that there is a video from a couple of years ago at Jeb's retirement as governor: Bush 41 is speaking at his son's departure, and he starts to tear up about this exact thing. He knew that the "Bush" brand was dead. Jeb was supposed to be the heir apparent.
GHWB knew in 2006, how much his son had fucked up his presidency, and also knew that Jeb's future as a politician was also over as a result.
