The Palm Beach Post has a good read on David Koch, the billionaire who, along with his brother, have helped "channel" the tea party movement, as the piece puts it, and is involved in funding the pro-Scott Walker side of the recall effort in Wisconsin:

"What Scott Walker is doing with the public unions in Wisconsin is critically important. He's an impressive guy and he's very courageous," Koch says after a benefit dinner of salmon and white wine. "If the unions win the recall, there will be no stopping union power."

Asked about union comments, Koch's spokeswoman is quick to moderate them.

"Koch companies support voluntary associations, and where they so choose, we recognize employees' rights to be represented and bargain collectively," Nicholas says in emailed remarks.

"We think the best workplace relationships are fostered when the employer works directly with its employees. It is a mischaracterization of our principles to say this means we oppose unions or want to dismantle all unions."
