U.S. Senate hopeful Ken Buck used to take a hard line on the issues of abortion and “personhood.” During the primaries, the Republican said that if elected, he would sponsor an amendment to the U.S. Constitution banning abortion and would support a proposed state law that would make some common forms of birth control illegal.

Now, as Buck seeks to woo unaffiliated and moderate voters in his attempt to oust Democratic U.S. Senator Michael Bennet, his positions are changing. On a questionnaire for a Christian family organization, Buck vowed support for “Personhood” Amendment 62, but he’s now against the measure, saying he hadn’t looked closely enough at the implications of the law, writes The Denver Post.

“This isn’t how I looked at the personhood amendment,” Buck says. “I’m not in favor of banning common forms of birth control.” He also says he would no longer introduce a ban on abortion and might even be willing to confirm pro-choice judges, another reversal of his earlier positions.

Buck made a campaign stop on Saturday in Fort Collins, hammering home his message of smaller government.

“This election is really about America and whether we’re going to change the direction we’re going: $13 trillion in debt, $100 trillion in unfunded liability,” he said, adding, “We can’t sustain that” (via the Coloradoan).
