In an AP story earlier this week, Rudy Giuliani explains his Democratic past (I know how you're feeling, gov) and is quoted thus: "I don't think anything separates us more right now between Republicans and Democrats than how we look at taxes. What we understand as Republicans is that, sure, the government is an important player in this, but we are essentially a private economy. What Democrats really believe is that it is essentially a government economy."
Couldn't agree more with the latter part of that statement, nor disagree more with the former. A much biggest difference? Democrats are convinced that George W. Bush is the greatest threat to peace in our time -- Republicans know that the threat comes not from Bush, but from radical Islam, and has since for long before Sept. 11.
