I do not think it means what you think it means

"It seems inconceivable that the Clinton administration would have intervened in Teddy Forstmann's social life simply because he was a prominent Republican. "

Many things are inconceivable about anything to do with the Clintons: Their election, twice to the White House and twice to the senate; that anyone anywhere takes them seriously about anything; that they geared up the Washington Post, the New York Times and the networks to slime Monica Lewinsky as a stalker when they knew she was just a compliant kid; that Hillary will be president. The list is endless.

Which is to say, it's not only coneceivable, it would be unsurprising. Hard to believe that two people could so easily render the U.S. a third world country, but you've seen it yourself.
