Its a non-issue. The number of ranchers that could posisbly affected is minuscule at best, and the law permitting the release of these Wolves also allows for any rancher that loses a cow to a wolf to be reimbursed by the state for their loss. A vast majority of these "ranchers" are millionaires and billionaires in the first place, and the loss of a cow to a wolf will be insanely rare. These animals will hunt deer, rabbit, and elk whose populations are literally out of control.
Most of the noise opposed to this release is generated by wildly ignorant or malicious people who don't even live in Colorado to wind up other reactionary, low-information people and make it look like liberals are releasing dangerous predators into a "red" part of the state to harm them.
Nothing could be further from the truth.
