Talk about strange bedfellows.

Charles Koch — one-half of the petrochemical billionaire duo that orchestrates a vast network of conservative causes — told ABC News in an interview Sunday that the top Republican presidential frontrunners are so bad Hillary Clinton might make a better option. 

Critical of the divisive rhetoric embraced by Republican candidates, Koch compared Donald Trump’s “monstrous” views on surveilling American Muslims to Nazi Germany, and called Ted Cruz’s promise to carpet-bomb ISIS “frightening.”

ABC News Chief White House correspondent Jonathan Karl asked the billionaire, “So is it possible another Clinton could be better than another Republican?”
