DENVER -- The leader of the "free the delegates" movement is a government teacher in the Denver area.

Gearing up for a fight at next month's Republican National Convention in Cleveland, Kendal Unruh is an American government teacher, RNC delegate and rules committee member from Castle Rock.

"We've all united in one common goal and that`s anyone but Trump," Unruh said.

Uhruh said she cannot and will not cast her vote for Donald Trump.

“He doesn`t reflect us. He doesn't reflect the principals of our party," she said. "He does not define what it means to be a conservative, and quite simply he can't be the face of our party and that`s what this is about."

Uhruh said in July delegates are technically free to cast their first ballot for whomever they want.

“There are no state laws that can actually bind a delegate to the outcome of the primary,” she said.

But she said the rules followers, as she calls them, are under the impression they are bound to the results of the primary election.

"There should never be a reason to make a delegate be locked into that vote,” Unruh said.

That's why she's trying to rally support to add a "conscience clause" to the convention's rules.

“All my clause is doing is, the permission slip from mom that is codifying a right that already exists with a delegate to unbind,” she said.

Unruh said support for the "free the delegates" movement has in one week gone from 30 to more than 400 delegates and alternates committed to denying Trump the nomination.

“He simply cannot win against Hillary,” she said.

But in order to get the clause in the rule book, she needs 57 of the 112 rule committee members to jump on board.

“I admit it's a steep uphill climb but I`m a mountaineer and I take things a step at a time,” she said.

Trump's campaign is said to be preparing a sophisticated operation to fight back, including an army of volunteers and paid staff to keep the convention's delegates in line.

Several members of the Colorado GOP did not reply for comment. When Unruh was asked if this is dividing the party, she said she believes it's saving the party.
