Author of "Citizen McCain" jumps ship

There’s an argument that all this compromise wasn’t necessary: some very smart political analysts believed from the outset that McCain could win the nomination by sticking with his old self. And they still believe that McCain won the nomination not because he gave himself over to the base but as a result of a process of elimination of inferior candidates who divided up the conservative vote, as these observers had predicted. (These people insisted on anonymity because McCain is known in Republican circles to have a long memory and a vindictive streak.)

By then I had already concluded that that there was a disturbingly erratic side of McCain’s nature. There’s a certain lack of seriousness in him. And he does not appear to be a reflective man, or very interested in domestic issues. One cannot imagine him ruminating late into the night about, say, how to educate and train Americans for the new global and technological challenges.

Now he’s back to declaring himself a maverick, but it’s not clear what that means. If he gains the presidency, is he going to rebel against the base he’s now depending on to get him elected? (Hence his selection of running mate Sarah Palin.) Campaigns matter. If he means “shaking up the system” (which is not the same thing), opposing earmarks doesn’t cut it.

McCain’s recent conduct of his campaign – his willingness to lie repeatedly (including in his acceptance speech) and to play Russian roulette with the vice-presidency, in order to fulfill his long-held ambition – has reinforced my earlier, and growing, sense that John McCain is not a principled man.
In fact, it’s not clear who he is.

What would it be ? An amoeba ?
