Most of them doubtless believed that poor Americans are shiftless, Palestinians are evil, and Iranians are crazed fanatics, and they were not paying to have their views challenged.
Still, he should have been more careful. Blaming the failure of 19 years of negotiation to bring a peace settlement in the Arab-Israeli dispute entirely on the Palestinians was not going to get him in trouble at home.
"The Palestinians have no interest whatsoever in establishing peace," he said, which would be seen as a distortion of the truth in most parts of the world, but it does no harm to Romney domestically. Indeed, lots of Obama voters think that too.
Same goes for the bizarre scenario he drew about the alleged threat from Iran. "If I were Iran - a crazed fanatic, I'd say let's get a little fissile material to Hezbollah, have them carry it to Chicago or some other place, and then if anything goes wrong, or America starts acting up, we'll just say, 'Guess what? Unless you stand down, why, we're going to let off a dirty bomb'."
This is only one or two steps short of expressing a fear of werewolves, but in the United States this sort of discourse is routine. Romney will not get into any trouble with the electorate for this "gaffe".
Where it all went wrong was when he said that "There are 47 per cent of the people who will vote for the president no matter what," referring to the Americans who don't pay income tax.
"There are 47 per cent who are with [Obama], who are dependent upon government, who believe that they are victims, who believe the government has a responsibility to care for them, who believe that they are entitled to healthcare, to food, to housing, to you-name-it."
The audience at the fundraiser obviously believes that, and it's likely that Romney believes it too, but it is simply not true. If all of the 47 per cent of Americans who do not pay income tax automatically vote for Barack Obama and the Democratic Party, then the Republicans can never win an election. At least not unless EVERYBODY who pays income tax votes Republican, which seems pretty unlikely.
It was especially reckless of Romney to couch the whole discourse in terms of who pays taxes or doesn't. This from a man who has refused to release more than the past two years of his own tax returns. Why endure all the criticism about not releasing the past five years, say, if there was nothing to hide in the returns for the preceding years? Like, maybe, the possibility that Romney paid no tax at all in those returns.
The people who pay no taxes in the United States are the very poor and the very rich, and Romney certainly falls into the latter category. If he paid no tax at all in 2007, 2008 and 2009, say, he would have fallen into the 47 per cent in those years. So should we conclude that he voted for Obama in 2008?
Probably not, and we can feel a certain sympathy for a man whose supposedly private remarks, shaped to appeal to an ultra-rich and ultra-conservative audience, have been dragged into the public domain. But he should have known better. Almost invisible to him, there was another group of people in that room who were not rich at all: the people who waited on the tables of the mighty. It was almost certainly one of those helots who took the video of his talk. They are getting in everywhere.
