It is when a president's DOJ uses RICO statutes to go after anti-abortion groups, or when a ban on a particular abortion procedure reaches his desk, or any other federal expansion or restriction of abortion "rights" or funding for same comes up. A lot of ground can be gained or lost in that area, depending on the inclination of the president.
It's fine if that's the way you see it, and if that's the most important issue for you. But I don't base my decisions on that alone. Yes, I'd like to see it elimated, but not I don't believe it will be. I think more good is done working at the local/personal level.
As for my choice for President, there are other considerations 1) electability, 2) fiscal responsibility, 3) the war on terror. I think Rudy carries the day with those.
Do I agree with him on every issue? No of course not.
