The Never Trump movement is rallying behind this non-politician as a contender to replace Donald Trump as the GOP nominee: Colorado high school teacher Kendal Unruh.

It’s summer vacation for Unruh, but instead of taking a break, she’s trying to take down Trump.

Unruh, a conservative activist, is a delegate on the Rules Committee of the Republican National Convention. She hopes to use her position within the committee to convince other GOP party members that delegates are not required to vote for Trump.

She wants the rules committee to switch to language that would clearly allow delegates to vote for the nominee of their preference.

“There is no language supporting binding in the temporary rules of the convention, which are the only rules that matter,” the Delegates Unbound group says on its website. However, the likelihood that the rules will change by this year’s RNC is, well, unlikely.
