What would McCain do to the Supreme Court?

Here is a well-written and interesting blog post about what a McCain presidency might mean for the Supreme Court. I also think this is an interesting way to look at the difference between Republicans and Democrats:

"I have long argued that the real difference between the two major parties lies primarily in the constituencies that they are forced to appease in order to stay in office. On judicial matters, the constituency that Republicans, including - perhaps especially - McCain, have to please is the religious right. No issue is more important to the conservative Christian base than control of the courts. The James Dobsons of the world are not stupid; they're politically savvy enough to know that they are one vote away from overturning Roe v. Wade and that McCain could appoint the justice who tips the balance."
