This is a good piece in Newsweek by Michael Tomasky: Mitt Romney: A Candidate With a Serious Wimp Problem:
“…But the new values surface often enough—his fondness for firing people, the way he made fun of NASCAR fans’ ponchos, his reminders to us that his friends are the people who own the teams, and now his putdown of an entire nation, which happens to be our closest ally—to suggest that they won the argument.
“[...] In some respects, he’s more weenie than wimp—socially inept; at times awkwardy ingratiating, at other times mocking those “below” him, but almost always getting the situation a little wrong, and never in a sympathetic way. The evidence resonates across too many years to deny. What kind of teenager beats up on the misfit, sissy kid, pinning him down and violently cutting his hair with a pair of school scissors—the incident from Romney’s youth that The Washington Post famously reported (and Romney famously didn’t really deny) back in May? The behavior extends, through more sedate means, into adulthood. The Salt Lake Olympics remains his greatest triumph, for which he wins deserved praise. But to many of those in the know, Romney placed a heavy asterisk next to his name by attacking the men he replaced on the Olympic Committee, smearing them in his book, even after a court threw out all the corruption charges against them.
“And what kind of presidential candidate whines about a few attacks and demands an apology when the going starts to get rough? And tries to sound tough by accusing the president who killed the world’s most-wanted villain of appeasement? That’s what they call overcompensation, and it’s a dead giveaway; it’s the “tell.” This guy is nervous—terrified—about looking weak. And ironically, being terrified of looking weak makes him look weaker still.
“[...] In a similar vein, it was breathtaking, and a meaningful window into his thinking, that he thought denouncing “Obamacare” to the NAACP constituted courage. That was the opposite of courage—an easy shot aimed at people who aren’t voting for him anyway. Going to the Southern Baptist Convention and telling them they’re all wet about Mormonism? Now that would be courage. Can anyone picture Romney doing that in a million years? The Mormon God will come down from Kolob before that happens.”
