Sen. Lindsey Graham Lindsey Olin GrahamMcConnell locks down key GOP votes in Supreme Court fight Will Republicans' rank hypocrisy hinder their rush to replace Ginsburg? Momentum growing among Republicans for Supreme Court vote before Election Day MORE (R-S.C.) on Thursday introduced a ban on abortions after 20 weeks of pregnancy, seeking to bring the bill to the Senate after it passed the House last month.

Graham, a Republican presidential hopeful, said he wanted to spur a debate on the issue of abortion, even if the new restrictions might not get through the Senate and would not be signed by President Obama.

“How many votes will it get, I don’t know,” he said at a press conference. “Here’s what I will predict: Over time, we will win.”

He challenged Democrats and opponents of the bill to “tell me the upside” of abortions after 20 weeks.

“I hope to have a discussion in America as to when do you become who you are?” he said. “If you have a soul, when do you have it?”

A vote for the legislation could be used against Republicans who are vulnerable in the 2016 elections.

Asked about this potential problem, Graham replied, “Don’t get in politics if you don’t want to talk about things like this.”

The bill has 42 Republican co-sponsors, including Senate Majority Leader Mitch McConnell (R-Ky.)

“He is very favorable to this bill. I think he’s a co-sponsor,” Graham said of McConnell. “And we’ll find time on the calendar. I can promise you a debate in 2015 and a vote.”

If the bill ever does make it into law, it has a challenging future in the courts. A federal appeals court last month struck down a similar 20-week abortion ban in Idaho for violating Supreme Court precedent protecting abortions up to the point of viability, considered to be around 24 weeks.

An Arizona ban was also struck down in 2013, and the Supreme Court declined to hear an appeal of that decision.

Ten states currently have 20-week abortion bans, according to the pro-abortion rights Guttmacher Institute.

But Graham expressed confidence a court would uphold the law. “I think science is on our side, and I think law will be on our side,” he said.

Since Roe v. Wade in 1973, Graham said, science has advanced and can now recognize that there should be a legally compelling interest for the government to ban abortions at the point where a fetus can feel pain.

NARAL Pro-Choice America President Ilyse Hogue accused Graham of using the bill to further his presidential bid.

“He is choosing to use his position in the Senate to advance an abortion ban to bolster his long-shot White House bid in a shameless play to early-state ultra-conservative voters,” she said. “We have seen this playbook over and over from anti-choice Republicans up and down the ballot.”
