"We're going to drill Hillary," Allen told Fox News at the Television Critics Association event for the show. "It will be horrible personally if Hillary continued [to lead the Democrats], but it will be great for the storyline if she continues."
Allen, 62, a Republican, didn't mince words with the subject of the GOP contenders for U.S. president, either. Specifically, he's not rooting for Donald Trump to take the lead.

"I sat with a group of liberal Jewish guys who said, 'When Trump starts to make sense, we know the world is upside down,' " said Allen, who pledged that he won't support Trump "until I see what's under that hair."
Allen said his candidate of choice is John Kasich, the Ohio governor who declared his candidacy for president on July 21. At the event, Allen described Kasich as "a Republican that a Democrat could vote for."
