LIKE SO MANY HAPPENINGS IN THIS ADMINISTRATION, IF YOU PUT THIS IN A NOVEL IT WOULD SEEM CRUDE AND UNREALISTIC: Obama slams billionaires at the home of a guy named Rich Richman. Who is . . . wait for it, wait for it . . . rich!

Unlike fiction, reality doesn’t have to be plausible. And boy howdy have we seen that these past few years. But this would be too heavy-handed for any editor:

Richman, who built his $10 billion company developing rental housing, lives in the Conyers Farm area, where the minimum lot size is 10 acres. Twenty-five donors paid $32,400 each to get their photo taken with the president. Others paid $10,000 for dinner.

While Obama was schmoozing — and the press pool was playing billiards in the basement — he was also soliciting donations for House Democrats in an e-mail.

“If Republicans win, we know who they’ll be fighting for,” Obama said. “Once again, the interests of billionaires will come before the needs of the middle class.”

Obama arrived from New York City — where he had attended a fundraiser with hedge-fund billionaires George Soros and Paul Tudor Jones — in a convoy of four helicopters that landed at the Greenwich Polo Club.

But not too heavy-handed for reality.
