As noted in an earlier post, I think Ron Paul's disavowal of the racist garbage published in his newsletters rings hollow. I also think his storming out of an interview in a huff when asked about them indicates someone temperamentally unsuitable for office, and consider about half of his ideas completely nutty. Drop a net over him and keep him away from sharp objects-grade bonkers. Would definitely not want to see him be President. However, and this relates to the attacks Wonderment suffered in praising Paul's anti-militarism, some of the things he says have merit and dismissing him and those things out of hand because we can point to some aspect of his thinking or his past that is repugnant serves to eliminate significant issues from discussion.
Democrats joining Republicans in wearing blinders and marching in lockstep with whatever politician gets onto the ballot and has a D or R after his or her name isn't something to celebrate. At some point voters may have to try to choose the lesser of two evils and try to prevent the greater, but denying that it is still an evil seems likely to be something that guarantees that things continue to get worse. Every candidate currently running for the Presidency is repugnant, and that emphatically includes the incumbent. I don't want to see any of these people in office.
