Jesus, you people are low.
The story behind that photo is well known. McCain had just given a speech endorsing George Bush as the nominee. Bush grabbed McCain’s hand and jerked his arm above their heads. McCain gritted his teeth and managed to say “It doesn’t go that high”. The picture is of McCain displaying solidarity the only way he can.
McCain has always been a tenacious warrior, but ultimately, he falls short as the conservative bellwether. Hopefully, theres some position in the party for him to utilize his talents. He would be a far greater asset as a VP IMO. Every president needs an effective attack dog now and again.
