"In fact it is likely Romney as President, will publicly support the pro-life position, unlike Hillary and Guiliani, who will be publicly pro-choice, and thus Romney is far better for the unborn than they are."
McCain, as much as I hate him, is pro-life. And has consistently been so. Huckabee is pro-life. Brownback is pro-life. Hunter is pro-life. Gingrich is pro-life (I think he'll run).
We're turning into Democrats here, supporting candidates because they "can beat [insert name of vilifed opposition candidate." Conservatives are supposed to care about the issues, not to just flock to rock star candidates.
President Hillary (and Guiliani for that matter) can do a lot of damage to the pro-life movement, such as successfully nominating rabid pro-abortion judges. It will set the movement back another 40 years. Therefore, I believe our chances are better with someone who is running on a conservative plank, including the pro-life issue, AND who can win.
If a proven conservative with charisma enough to defeat Hillary enters the race, I will be first in line to support them.
