The young Americans trying to stop Ireland from voting Yes to abortion

With just days until Ireland votes in a referendum on whether to repeal the Eighth Amendment to the constitution -- which places the right to life of an unborn child on equal footing with that of the mother -- campaigners have become increasingly confrontational in their tactics.

If a majority vote Yes on Friday, Ireland is expected to enact legislation that will allow for terminations up to 12 weeks into a pregnancy. A No vote would keep the country's abortion laws -- some of the most restrictive in the developed world -- in place.

But not all of those targeting voters with leaflets, placards and social media posts are Irish.

Faulkner, 23, and Berning, 25, are founders of the Colorado-based anti-abortion group Let Them Live. They've travelled to Ireland for the month leading up to the historic poll to "sway the voters to vote pro-life and hopefully keep Ireland pro-life."

"Basically it's a Roe v. Wade, but Irish style," Faulkner told a group of American students she was attempting to recruit for the journey, referring to the landmark 1970s court case that made it legal for women across the United States to have abortions.

When the couple (both associated with the US-based conservative nonprofit The Leadership Institute) launched a $10,000 crowdfunding campaign to finance the trip, they had written they'd be volunteering with Ireland's Pro Life Campaign. But after they experienced an "unexpected" backlash from Irish pro-repeal groups, who said they weren't welcome and threatened to report them to immigration, they changed that description, removing any mention of joining the campaign in an official capacity.
