How do you become unified around your opposition to abortion and your opposition to federal spending? Well, that's rhetorical. Jesus. Jesus was anti-abortion. Roe means that abortions are legal in every state. Which is anti-states' rights. So we need more power for the states, and less for the federal government. Which means that anything the federal government does sucks.
There are 41 Republican senators. I think Hutchison, Murkowski, Collins, Snowe, and Specter are the only ones who are pro-choice. All, conveniently, are either women or senators who are described as "moderates" by the MSM or "traitors" by the right. It's reasons like this that Republicans will have trouble in the future, given that the country will likely be 60/40 in favor of allowing abortions by the time Obama ends his term(s).
This is one reason it's so hard for me to take the majority of Republican bloggers/writers seriously. I'll read a fairly lucid argument concerning the perils of certain stimulus measures, and it'll cause me to think a bit more, do a bit more research. But then I'll scroll down and see that only an hour earlier, that same blogger wrote about how Obama's abortion position is pro-death. It's like if at the end of an English class, your professor said "I think anyone that listens to rock music is hopeless."
