Hug = Kiss Ass
I like John McCain and might have even voted for him last time if was on the ballot. While Bush has slipped into several unclean snafus John McCain was about the only Republican to question his ethics. He was a thorn in Bush's side. I liked him for that.
So, why is he kissing up to the President now?
I think for one thing John McCain has a soft spot in his heart for the underdog, which Bush metamorphosed himself into. And number two is I think now he feels, for the survival of the Republican Party that they need to show a some solidarity to their "main man".... which might, in the long run be an investment if he runs again.
