1) He's going to leave politics and is no more use to her
2) He's going to run for President (since Obama is not an NBC, why should the Governator hold back?) and she's dying of embarrassment.

LOL. I remember when T3 came out and in the movie when Arnold as a Terminator arrives from the future and they had digitally placed his current face on a massively computer enhanced naked body that looked like him when he was 25 years old.
And Arnold was trying to claim in the interviews it was his real body and hadn’t been altered in anyway with technology.
That NOW picture came out soon after T3 and the National Equirer called him the “Tummynator”.
I never looked even close to that good that young, but now I don’t feel so bad about how I look today, and I am 9 years up on him.
