Just so we’re clear, if this guy wins the Republican nomination, I walk:

Mitt Romney was firm and direct with the abortion rights advocates sitting in his office nine years ago, assuring the group that if elected Massachusetts governor, he would protect the state’s abortion laws.

Then, as the meeting drew to a close, the businessman offered an intriguing suggestion — that he would rise to national prominence in the Republican Party as a victor in a liberal state and could use his influence to soften the GOP’s hard-line opposition to abortion.

He would be a “good voice in the party” for their cause, and his moderation on the issue would be “widely written about,” he said, according to detailed notes taken by an officer of the group, NARAL Pro-Choice Massachusetts.

“You need someone like me in Washington,” several participants recalled Romney saying that day in September 2002, an apparent reference to his future ambitions.

Romney made similar assurances to activists for gay rights and the environment, according to people familiar with the discussions, both as a candidate for governor and then in the early days of his term.

People can change their minds on an issue, and if Mitt Romney has had a genuine change of heart on abortion, then that’s great.  But how can anyone possibly trust this man?  He’s a chameleon who changes his tune to suit his audience.

On the other hand, though Rick Santorum is not my first choice at the moment, he’s the only candidate who puts social issues first on his website.  He’s by far the most passionate defender of the unborn we have in this race, if not the country.
