I haven’t weighed in on Romney’s awesomely awful intervention on events in Egypt and Libya; with even Republicans joining in the chorus of shocked disapproval, not much I can add.

But maybe I can say something about why this matters for the campaign.

There will probably be some voters moved directly against Romney by this spectacle, and none moved toward him. Yes, there are quite a few Americans who are willing to believe that the man who has been president for three and a half years — and who killed Bin Laden — actually sympathizes with terrorists. But everyone in those fever swamps is already an Obama-hater, and Romney has just made himself look small and hysterical to everyone else.

But the real impact probably comes via the press.

I’ve seen some comparisons between Mitt Romney’s position right now and that of George W. Bush after the Democratic convention in 2000, and by the numbers there is some resemblance. But what really happened in the final months of that election? The answer — not a popular one with journalists, but very obviously true to anyone who lived through it — was that the press took sides. Reporters liked Bush and didn’t like Gore, and as a result they treated Bush with kid gloves while gleefully passing on every smear against his opponent (“Gore says he invented the internet!” No, he never did).

That probably wasn’t going to happen this time in any case. But now Romney has really ensured that everyone in the news media, the GOP propaganda organs aside, is going to view him with distaste and alarm — as well they should.

Romney could still win, but he has just made it even harder for anyone to consider him suitable for the job.
