Politically, the end of Roe would crack open the Republican coalition in the country and on Capitol Hill.

Eleanor Clift has an interesting column in Newsweek entitled "The Republican Party is full of secret pro-choicers. If Alito helps to overturn Roe v. Wade, it could crack open the GOP coalition in the country and on Capitol Hill."

In it she writes at one point:

A pro-choice Republican who spoke with NEWSWEEK but didn't want her name used said she is more worried about Alito after hearing him testify, and wishes the Democrats would spend their time finding a candidate to beat Hillary Clinton in the primaries "or we're going to get four more years of judges like this." She thinks that to win the White House the Democrats need a more centrist candidate than Clinton. "The math is against her." (That debate is raging within Democratic circles, but no candidate has yet surfaced who could plausibly overtake Clinton, given her rock-star hold on party activists and the esteem in which she and her husband are held by African-American voters, a core Democratic constituency.)

It's pretty clear where Alito is headed on abortion rights. He refused to say whether he agreed with the characterization of the 1973 Roe ruling as "settled law," that couldn’t be re-examined. Now that the GOP is within striking distance of overturning Roe, they're having second thoughts. The public is not ready to abandon the landmark case legalizing abortion, and neither is the Republican Party. They used abortion as a wedge issue because the politics worked; they really didn't think abortion would ever be banned. "Any activist will tell you they'd rather have the issue out there than to have it resolved," says this pro-choice Republican, who has worked on the Hill and for various Republican interest groups. "If Roe were overturned, we'd be electing Democrats as far as the eye can see."

According to this source, even committed right-to-life activists don't want Roe struck from the books before society is ready. "They think if given the time, they can change the culture. I think they're deluded, but they know it's going to take time."

So what is the most likely scenario? The fight over Roe is not imminent. The more immediate challenge will be whether underage pregnant women will have to notify their parents of abortion plans, and extending the right of privacy to minors. "Would we have had Sandra Day O'Connor with us on that?" says the pro-choice Republican. "I'm not sure." She expects Alito to vote to erode Roe, and then the argument will be, sometime in the not too distant future, that the ruling is a shell, and it will be overturned.

Then the battle moves back to state legislatures, and some places—like Utah, Louisiana, Missouri, Alabama, Oklahoma and South Dakota—would outlaw abortions while other states, like New York and California, would be decried by the Right as "abortion mills." Politically, the end of Roe would crack open the Republican coalition in the country and on Capitol Hill. The party is full of secret pro-choicers, Republicans who signed on to a package that included the pro-life position with the belief that it would never happen. They've kept their mouth shut all these years, but they'll be mad as hell and not willing to take it any more. "Even if there's no right to privacy in the Constitution, there ought to be," says this pro-choice Republican. "It's an American virtue.”
