Albert Mohler echoes my thoughts and approach exactly (though more eloquently):
I have refrained from extended comment on the health care reform bills—not because I do not have multiple concerns about the bills, but because I recognize that committed Christians can and will disagree over the political and policy issues involved. The trip-wire for me is the issue of human life. The current bill spells disaster when it comes to abortion. I cannot remain silent in this crucial moment where the sanctity of human life is at stake.
Read his whole commentary, where he quotes Charmaine Yoest, president of Americans United for Life, who argues that the bill represents “the single greatest expansion of abortion since the 1973 Roe v. Wade decision.”
