Elizabeth Drew, author of the 2002 (with ’08 paperback update) “Citizen McCain,” tells why she used to find him refreshing, but sees nothing there any more to like. Bottom line:

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.
