Hardly anyone who supports abortion will ever be able to change their mind on it for the better, for doing so would imply that they'd have to admit that they were messed up in the head (to say lightly) enough to support the murder of helpless babies. Most of humanity does not have the humility to face their own ugliness and fallenness. Thus, you get sorry saps that will perform the most complex of mental gymnastics to justify their beliefs. They'd rather commit to evil and claim it's justified and good in order to avoid admitting their wrong instead of turn from it in humility and admit their corrupt nature. Edit: however, God still loves them and accepts them as they are. Christ died for all sins. They just need repent and believe. God, in His good grace, will transform their hearts to good.
