Why all the assumptions that Gravel has a chance in hell of getting the nomination? Whatever else might discredit the LP, Gravel's seeking its nomination does not, unless he actually gets it. As the LP spokesman pointed out in a press release, in order to seek the nomination, a person has to meet the Constitutional requirements for President, and be an LP member. The party has open membership, and does not reject potential members. So it has no mechanism to prevent people from seeking its nomination, but that doesn't mean they will get it. I don't see why Gravel's silly decision to seek the LP nomination is supposed to allow me to conclude that there's something wrong with the party. Now, if he were to get it...
On the other hand, there are some rightists and conservatives being openly discussed for the nomination. Bob Barr stands a far greater chance than Gravel of receiving the nomination. Barr in the past was noted for his support of the war on drugs. Yet it seems there is much more hysteria around Gravel's candidacy (who has no chance of getting it) than Barr's. Why is the leftist invasion worse than the rightist invasion? In fact, the party has for many years been seen as an adjunct of the right. I don't see why Gravel is what sets people off.
