The Humane Society Legislative Fund issued an endorsement for Barack Obama, who supports abortions throughout pregnancy for any reason and has been criticized for opposing anti-infanticide bills in the Illinois legislature.
The group says it has never made an endorsement for president before, though it has backed hundreds of candidates for Congress.
"But, in an era of sweeping presidential power, we must weigh in on this most important political race in the country," the group said.
"The Obama-Biden ticket is the far better choice on animal protection," the group says, adding that it only "evaluates candidates based on a single criterion: where they stand on animal protection policies."
"The disconnect is insane," Stanek says in response. "The Humane Society has no problem promoting single issue voting" while pro-life advocates don't get equal treatment.
