Even Bopp says the drive to end abortion is seen as a two-step process: First, overturn Roe v. Wade, which would return abortion law to the states; and second, create consensus for a constitutional amendment outlawing abortion.
However, one cannot deny that it certainly would be preferable for the pro-life movement to elect a president who agrees to work towards passing an amendment in the first place -- even if it is seemingly futile at present. Fred's statements imply that he will not use his presidential position to further that cause. Romney will. Hunter will.
In fact, Fred has a laissez faire attitude regarding social issues in general as evidenced by his "so be it" statement regarding gay marriage as well. We don't have to settle for indifference when we can have resolve to lead the cause.
Having said that, even prominent pro-life leaders like Jim Bopp realize that the pro-life community should be sophisticated and savvy enough to understand how a pro-life politician has to advocate for the possible, and must not allow the perfect to be the enemy of the good.
Thank you for your intellectual honesty. I hope it spreads.
