Not necessarily the man himself, but the whole republican party is pretty toxic. It seems to be a mixture of 'screw the weak' and 'Jesus is Lord' with a dash of just plain nuts. This is how it appears to folks overseas anyway.
When Bush was re-elected, for instance, it was genuinely baffling. Not that there was anything good about Kerry, but... seriously? That guy again? And since then the republicans just seem to have become more and more caricatured. The whole Sarah Palin thing would have been funny if we weren't talking about the upper echelons of politics in America.
