This is related to my post below. The Hot Air piece did include a section on abortion. However, this is a much more comprehensive article on that subject in itself, so it's a must read if you consider yourself pro-life and are considering voting for Obama this year.
The most eye-catching indictment is that Obama intends to sign the freedom of choice act as soon as he's in office, which would make abortions a right in federal law, provide public funds for abortions (though public health aid), and remove conscience clauses that allow physicians and nurses to opt out of such procedures on moral grounds.
There's lots more, including analysis both on what he would do as president and what he has already done as a senator (state and national).
The bottom line is that Obama is in no way, shape, or form a pro-life candidate. If that platform is important to you, then there is no justifying a vote for him.
