There is an article on BBC News site titled "McCain's evolution". But if you read it carefully, you'd get to the same conclusion: the title should be "McCain's Devolution". I bet that the author ( Matt Frei ) is a conservative of sorts ... and an admirer of GW "The Disaster" Bush.
Just to get a taste of the article: "So Mr McCain went to the other extreme and chose a pit-bull with lipstick." Haaaaa haaa haaaa ... pit-bull? Rather an empty-headed bimbo playing beauty contest tricks (see the now famous winking). But hey, Matt Frei is entitled to his tastes ... if he only would spare us the "Obama was frozen like a moose caught in Governor Palin's cross hairs".
