Abortion -- How Will It Play in '08?

Abortion opponents are preparing for their annual March for Life through the streets of the nation's capital today.

Today is the 34th anniversary of the Supreme Court decision that legalized abortion, and those opposed to the procedure will be rallying on the National Mall before marching down Constitution Avenue.

While tens of thousands are expected to gather outside of the Supreme Court, others abortion opponents are taking part in news conferences or receptions where they'll voice their opposition to abortion.

President Bush is expected to address the anti-abortion demonstrators by telephone from the presidential retreat at Camp David around noon.
