On the one hand, the parties are effectively the same. On the other hand, supporting Badnarik and allowing Kerry to win is fine, as the inherent tension between a Republican Congress and Kerry will insure general gridlock. The two positions are mutually exclusive, yet uttered almost in the same breath.
Buzz I will tell you my opinion on the above.
First though, realize I am not a Libertarian, I am a conservative. Previously I have considered myself a conservative Republican, but such an animal ceased to exist in 2000 when Bush took control.
Anyway, I do feel that under Bush, the line between the parties has become blurry. We have seen expansion in the size of government under Bush and we have seen expansion of social welfare. Both of these things are positions the Democrats have traditionally supported. We have also seen increased government intrusion into our lives through such legislation as McCain Feingold and the Patriot Act. This is also something I would have expected a Democrat and not a Republican to have supported.
So I do think that the parties are becoming more similar.
Now I also think that while the parties are very similar, having one in control of Congress and one in control of the presidency would ensure gridlock.
The gridlock would ensue not because of party differences, but simply due to partisanship.
I think McCain Feingold, for example, would have never been passed into law if different parties controlled the branches of government. I think one party would have opposed it simply because the other party suggested it.
Medicare Reform and No Child Left Behind would not have made it either if different parties had controlled the Congress and Presidency.
So I dont think any mutual exclusion of these ideas exists. I just don't think you are looking at it from the right angle.
