McCain no doubt understood how difficult it would be for Hagel to endorse him, yet their differences were what would make the endorsement so valuable. From 2004 on, McCain, in his desire to win the nomination, had embraced Bush’s policies ever more zealously, while Hagel had become the Administration’s most severe Republican critic. Although he has frequently voted with his party on domestic policy, his views on foreign policy represent a bold departure from those of the Administration, and his willingness to take Bush to task publicly has alienated many Republicans. In some ways, Hagel is far more of a maverick than McCain has ever been, and his endorsement would likely sway independents whose votes McCain probably needs in order to win.
And:
Hagel’s unwillingness to endorse McCain is generally perceived to be a result of their ongoing disagreements over the Iraq war. But he told me that the gulf between them is much deeper: “In good conscience, I could not enthusiastically—honestly—go out and endorse him and support him when we so fundamentally disagree on the future course of our foreign policy and our role in the world.”
And finally:
For Hagel, almost as disturbing as Palin’s lack of experience is her willingness—in disparaging remarks about Joe Biden’s long Senate career, for example—to belittle the notion that experience is important. “There’s no question, she knows her market,” Hagel said. “She knows her audience, and she’s going right after them. And I’ll tell you why that’s dangerous. It’s dangerous because you don’t want to define down the standards in any institution, ever, in life. You want to always strive to define standards up. If you start defining standards down—‘Well, I don’t have a big education, I don’t have experience’—yes, there’s a point to be made that not all the smartest people come out of Yale or Harvard. But to intentionally define down in some kind of wild populism, that those things don’t count in a complicated, dangerous world—that’s dangerous in itself.
“There was a political party in this country called the Know-Nothings,” he continued. “And we’re getting on the fringe of that, with these one-issue voters—pro-choice or pro-life. Important issue, I know that. But, my goodness. The world is blowing up everywhere, and I just don’t think that is a responsible way to see the world, on that one issue. And, interestingly enough, that is one issue that stopped John McCain from picking one of the people he really wanted, Joe Lieberman or Tom Ridge”—the Independent senator from Connecticut and the Republican former governor of Pennsylvania. (Both men are pro-choice.)
