It is a different thing to change ones mind and have a reason than to say you never were.
Not sure what you mean. Romney says he was flat wrong when he held a personal pro-life stance but politically upheld the ruling under Roe.
On top of that, Thompson said the same thing. That he was against abortion personally but believed women should have the right to choose and the state should not interfere.
I don’t see what’s wrong with either men changing their minds on the issue. Frankly, I welcome it.
