Obama really excels at it. I was a kid during Reagan's day, so I'm not sure if that was the key to his success. But I watched Obama's speech yesterday, and he did it again. His basic pose is--"I'm willing to concede your good will, and maybe even a couple of periphery issues." When his adversaries can't do the same, they just look small-minded.
It's almost unfair to people who disagree with him--if I truly believed that abortion was the murder of children, I don't think I'd be interested in trading "fair-minded words" with pro-choicers. It's murder, and I think I'd pursue it with exactly the sort of zeal as those who were booing Obama. But that's my perspective, and my outlook--obviously it isn't the outlook of all pro-lifers. I'm just saying, I can see why you might be an extremist on the issue.
Politics aside, I think you have to give Obama credit for stepping right into the issue. I've seen weaker politicians drowning in handlers, reading from a carefully prepared text which fails to acknowledge the elephants dancing in the room. Obama, like he did in his race speech, went right at it. It likely won't please a lot of folks on either side, but if your goal is to grow the base, and expand the party, you've got the best man for the job--even if it, at times, grates on people like me. But, hey. Expanding the party isn't my job--it's his.
