Koch, his brother David and their team have identified five candidates who have the right message and “a good chance of getting elected,” he told USA TODAY in an exclusive interview at Koch Industries’ headquarters. They are Wisconsin Gov. Scott Walker, former Florida governor Jeb Bush and Sens. Ted Cruz of Texas, Rand Paul of Kentucky and Marco Rubio of Florida.

“Those are the ones we have talked to the most and who seem to be the possible leaders,” he said.

“What we’ve told them all is that right now, we’re not supporting anyone,” Koch said. “We’re telling them that if they want our support, one way to get it is articulating a good message to help Americans get a better understanding and a better appreciation of how certain policies … will benefit them and will benefit all America.”
