Lots, but mostly we want a passionate pro-life president that will do everything he can to sell and promote life to America, a candidate's campaign and positions signals what he will use the world's greatest bully puppet for, and what he won't.
There is abortion at the federal level in regards to foreign policy, military hospitals and other federal health law and hospitals, budget items, all kinds of things, we do not plan to elect people who's politics go against ours, because you want to pretend that a president has no effect on them.
Could a president be much more pro life than GWB was??? How many abortions was he able to stop, other than by the force of personality (which I do not at all demean)?
