Barack Obama has an ongoing controversy over his vote against an anti-infanticide bill. His pick for VP (Joseph Biden) has a similar track record (LifeNews):
[Biden] received a pro-life voting record of 0 percent from the National Right to Life Committee for 2007-2008.For example, Biden voted against a bill that would add a criminal penalty for harming an unborn baby during a crime.Before that, Biden compiled records of 0 percent, 16 percent, 0 percent, and 22 percent with the pro-life group in previous Congressional sessions. His support for a ban on partial-birth abortions represented the only time he voted with the pro-life side -- with Biden voting repeatedly to force taxpayers to fund abortions at home and abroad.
Biden threatened to filibuster Samuel Alito's supreme court hearings over abortion rights while applying a different standard to the nomination of forthrightly pro-abortion Justice Ginsburg.
I suppose birds of a feather flock together ...
I am curious why anyone thinks McCain will change anything about abortion. Reagan and Bush 2 campaigned on a promised constitutional amendment, but neither took any action once elected.
In regard to McCain, I don't expect that he'll make great changes to the constitution. However, I anticipate that he will veto abortion promoting legislation and will nominate significantly better judges that Obama.
