Sorry Starkers, but you are basing your choices are things that are the least likely important things one should be looking for in a Presidential Candidate.
So a bad temper, losing the plot under pressure, lack of integrity and hair-brained ideas/ideals are things one should look for in a President and VP???? Would you work for an employer who exhibited all these traits?? Would you marry a woman who also exhibited all these traits??? I don't think so, and while the relationship may be different, if you vote that pair in it's something you'd have to live with until the possibility of divorce came up in 4 years... yes, 4 loooooong years. Not something I wanna get wrong!
OK, so I reckon McCain sounds like a squeaky voice pimp and speaks like he has a stick shoved up his butt, but that is not the reason I do not like or respect him... though I would imagine that, combined with temperamental issues (with an emphasis on the mental), his squeaky pimp-like voice would command little respect from foreign leaders/diplomats who expect to be dealing with a rational and reasonable man of strength and character.... and in this ever shrinking world of internationalism, that IS an imporatant issue, don't you think! It's not like it was back in the Dark Ages when National leaders rarely, if ever, met the leaders of other States or Principalities... so yes, since the advent of international flight and instant communications, it is important that other world leaders do not judge you on the character of a plot losing bad tempered old bastard with a squeaky voice.
Of course domestic policies are important to you, but in the much bigger picture a President is responsible for dealing with both domestic policies and foreign policy /affairs... and to date McCain has failed to show that he is the right man for the job, on both counts. On the other hand, however, given his public approval rate, Barack Obama has proven that his policies have widespread support, as does his character, both in the US and overseas. A recent poll in Australia had Barack Obama at 87% as preferred US President... with John McCain on a paltry 13% Apparently, the UK and New Zealand registered similar figures...
... and it doesn't matter how the World views John McCain, so long as a handful Stateside happen to like him?????
