It looks like David Koch has left the reservation:
In the interview with chief White House correspondent Jonathan Karl, which aired on ABC's "This Week With George Stephanopoulos," Charles Koch said Bill Clinton had done a better job than George W. Bush in controlling government growth while president.
"So is it possible another Clinton could be better than another Republican?" Karl asked.
"It's possible," Koch responded.
"You couldn't see yourself supporting Hillary Clinton, could you?" Karl pressed.
Koch responded: "Well, I - that - her - we would have to believe her actions would be quite different than her rhetoric, let me put it that way. But on some of the Republican candidates we would - before we could support them - we'd have to believe their actions will be quite different than the rhetoric we've heard so far."
Now, as Josh Marshall pointed out, this doesn't mean that Koch actually supports Clinton. But he's not actually supporting Trump either. This is getting pretty interesting.
