Andrew Sullivan is an expat Brit, blogging pioneer and defier-in-chief of American political stereotypes. He is an economic conservative (anti-tax), a social liberal (soft on drugs) and a foreign policy hawk (pro-war). He endorsed George Bush in 2000 and John Kerry in 2004. Barack Obama is his preferred Democrat candidate in 2008. So he is either confused, a hypocrite or a champion of honest non-partisanship – depending on your point of view. He is also gay, a practising Roman Catholic and HIV-positive, a set of credentials he routinely deploys in arguments to confuse atheist liberals and evangelical conservatives.
