I wonder what that description of her position means to her.
She's honest.
Lots of people call themselves "pro life" up until the point they're faced with an unwanted pregnancy. Maybe their teen daughter gets knocked up by a guy with gold teeth and a face tattoo. Or the wife had a drunken affair on a business trip. Or their birth control failed. Or the baby is severely malformed. Or they can visualize any of these things happening. And on and on. At this point, they become "uneasily" pro choice.
There's more of these people out there than many realize. That's why abortion is still the law of the land. Because people generally want it to be, even if it makes them "uneasy."
