Paul, you bring up a good point...what would it take to get someone who is conservative on a lot of issues to vote for a Democrat. First of all, if it's Hillary, I would definitely vote for whomever had the best chance of defeating her.
But beyond that there's a dilemma. Personally, I think a partial birth abortion ban should have been signed by GWB immediately. What worse terror is there then maiming and then murdering pre-born infants? But, if the Republicans get too cute in their hedging on abortion to get "moderate" votes, and I feel (like in Massachusetts) they aren't going to make lots of abortions illegal, other issues matter. And the border is a huge one.
It's not just that I don't want foreign citizens to move here without developing American values, it's that I really don't like globalism, and think all borders (not just ours) need to be enforced and respected.
