-- It's not over until it's over -- at least, that's what some Republican delegates are saying.
This was the group's second conference call in four days, following a Thursday night call with about three dozen delegates. This effort is spearheaded by two Colorado delegates.
Speakers on the call encouraged participants to start "traditional grass roots campaigning" for the idea of unbinding delegates, calling for delegates to send information from their home states and for participants to write letters to the editor and call in to talk radio.
Still, the group is starting from scratch on what would be an unprecedented task.
"As delegates, you were not chosen to be rubber stamps," said Colorado delegate Regina Thomson, a leader on the call. "Down-ticket Republican candidates in every community are counting on us to do the right thing."
"My guy is off the stage," said Brita Horn, another Colorado delegate bound for Ted Cruz. "Based on old rules, I have no vote. It won't count. Why not support being unbound and vote freely?"
But some delegates said they feared retribution from state party leadership. One delegate from North Carolina said they were under "direct threat" from their state party -- a potential $10,000 fine if they voted against their binding.
Kendal Unruh, a member of the convention's rules panel, argued that delegates are already free to vote their consciences, but an explicit change in the rules will make them feel more comfortable doing so.
"I'm giving people a permission slip to unbind," she said about the potential rules change.
"I’m going to be on this phone day and night solidifying my votes," she said on the call. "I believe that it's my duty to solicit and get the votes."
"You’ve got your work cut out for you,” Thomson quipped back.
