Oh yeah, the Internationalist John F'in Kerry will make a much better President for our country than that nasty Statist, George W. Bush. /sarcasm
If the republican does it, you not only get the same results, but worse, you have destroyed the concept of what republicans are supposed to stand for.
Worse still, you have destroyed the fundamental concept (necessary to human survival, in fact) that reason and logic are efficatious in dealing with the world around us.
Putting it another way, we know that the democrats want to turn America into a socialist country, and you vote for them, you always get more socialism. Logic and reason are intact. The idea that the other party is somehow "different" is still intact.
But when you vote for a republican like George Bush (either one) who claims to want smaller government and more freedom, but gives us massive increases in government and draconian restraints on freedom, then two things have been destroyed: 1. The idea that the republicans are any different than the democrats, and 2. The idea that logic and reason are good tools to help you make the choices you need to survive.
