Thing about those voting for libertarian et al, that's probably a good, sound choice in normal times, but problem is now it's really tricky when realistically at least this time round that doesn't stand a chance of success, particularly as this is the most important and crucial election in US history ever, where the all important objective has to be getting Bush and his entire gang of evil Neocons out of the White House and out of our lives, in order to prevent them forming the US in their absolutely and totally lunatic and evil image of an intolerant and totalitarian state of the unfree at home, and total armageddon in the world.
Kerry may not be your favorite choice, but he is the only chance we have of getting rid of Bush.
Besides, quite honestly, while I personally think Kerry will do a decent job, there really is nothing anybody could possibly do worse than what Bush and gang have perpetrated in every single regard.
