Something you should see

Here are some key excerpts about McCain from the new expose of him in RollingStone:

"At least three of McCain's GOP colleagues have gone on record to say that they consider him temperamentally unsuited to be commander in chief. Smith, the former senator from New Hampshire, has said that McCain's "temper would place this country at risk in international affairs, and the world perhaps in danger. In my mind, it should disqualify him." Sen. Domenici of New Mexico has said he doesn't "want this guy anywhere near a trigger." And Sen. Thad Cochran of Mississippi weighed in that "the thought of his being president sends a cold chill down my spine. He is erratic. He is hotheaded.""

In April 2007, when a voter at a town-hall session asked him about his policy toward Tehran, McCain responded by singing, "bomb bomb bomb" Iran. The loose talk was meant to incite the GOP base, but it also aggravated relations with Iran, whose foreign minister condemned McCain's "jokes about genocide" as a testament to his "disturbed state of mind" and "warmongering approach to foreign policy."

"He's going to be Bush on steroids," says Johns, the retired brigadier general who has known McCain since their days at the National War College.
