election year revelation

My brow has a few added furrows from thinking about how hot-button issues figure into my voting this November. Abortion rights, for example. I don't like abortion. But, I also generally don't like Republican policy. So how does one reconcile these two issues in the ballot booth?
Well, people, let's talk it out.
Say McCain gets elected, puts another strictly conservative judge into the Court. Roe v. Wade gets overturned, right? Wrong. Abortion rights don't really hang on that one vote, as conservatives would have you believe in an election year. Don't believe me? Okay, so let's say Roe v. Wade does get overturned.
Then what? Well, the states get to decide individually whether abortion is legal. Yep, that's right. The battle is not won; it is merely passed along. Let's face it: most states would keep abortion legal.
So, Catholics, your vote for McCain is not a vote to end abortion.
Alternatively, Obama wants to offer prenatal and maternal support, more expedient adoption, and maternity leave laws as a way to pre-empt abortion. Does that make great, great sense to anyone else?
Please take a close yet holistic look at your values and see how they align with each candidate. (I'm thinking feeding the poor, I'm thinking the value of life, including those fighting in faraway countries...)
