Ted Cruz Believes 'Donald's Calculator Is Missing a Few Keys'

— -- Sen. Ted Cruz made it clear today that he has not warmed to his chief rival, Republican front-runner Donald Trump.

In addition to slamming Trump's delegate calculations on the campaign trail, Cruz also expressed his lack of interest in being Trump's vice president.

"I have zero interest whatsoever," Cruz said when asked via video from an audience member during the "Good Morning America" town hall at ABC News’ Times Square studios.

"There are a lot of reasons, but perhaps the simplest is that if Donald is the nominee, Hillary wins, by double digits," Cruz said.

"If Donald's the nominee, he loses. If I'm the nominee, we win.”

Even though Cruz won the delegates that were up for grabs in Wyoming this weekend, he still trails Trump in the delegate count.

"Donald's calculator is missing a few keys," Cruz said in discussing Trump's prospects of getting to the required 1,237 delegates in order to secure the nomination.

An ABC News analysis has Trump with 756 total delegates and Cruz with 559 total delegates, with fellow candidate Gov. John Kasich holding onto 171 total delegates.
