Here is another bit you can check: "...during the early nineteen-eighties John McCain sat on the advisory board of General John Singlaub’s U.S. Council for World Freedom—the American outpost of the World Anti-Communist League, a sort of clearing house for former Nazi collaborators, Central American death-squad leaders, and assorted international thugs." (from New Yorker: Beyond the Palin - The New Yorker - MSNBC.com)
Again, though, I say these associations are valueless.
For the record, I again state that I don't trust any politicians. I am sympathetic with the idea of being anti-government because you can't seem to trust anyone in the government. Indeed, anyone in a position of power is suspect, or so it would seem. Based on ideology alone do I feel the best though slim chance of government according to my wishes and therefore is McCain still the best candidate of the two.
