Ron Paul seems an honest man, more so than the average politician, but I doubt electing him as president is the best thing one could do. Most of his speech can be summarized by the following sentence: "Follow the constitution, damn it!". It gets boring after a while, let alone if we have to hear that stuff for four or eight years.
Also, I really wonder whether retreating from the NATO and the UN is going to make the world a safer place. Oh well, at least he's not a religious zealot like most republicans.. most notably Huckabee. Besides, I wouldn't elect someone who's 72. We don't want anyone dying in office, right?
If I were American, my vote would go to cakefarts. He's got issues I can agree on (healthcare, immigration), is fairly progressive in terms of ideology and seems way more straightforward than Clinton.
