Since when did abortion become a need? I thought it was a "choice."

President Obama's budget proposal for 2010 includes one item (using tax dollars to fund abortions in the District of Columbia) which will anger prolifers and another (not seeking to overturn the Hyde Amendment) which will anger pro-choicers. The Center for Reproductive Rights has issued this press release already claiming that by not providing tax dollars for the abortions of poor women Obama is "ignoring the health care needs of millions of women." I couldn't find the word "choice" anywhere in the press release where as the word "need" was. I always thought those favoring abortion rights thought of it as a "choice." Abortion now (or at least for CRR) appears to have morphed into a "medically necessary health service" which "women need." When taxpayers aren't forced to fund this "need," women are discriminated against and their well-being is threatened.
