They endorsed Kerry and Obama. You don’t find it extreme?
The American Conservative has always been anti-neocon and anti-globalist as they believe such policies are extremely detrimental to America’s long term interests. I’ve always despised both Bush jr and John McCain myself, though not to the extent of preferring Kerry.
But to be honest I myself was open to Obama when he first ran because I hated McCain that much. For all the evil Obama did domestically, I do give him credit for at least moderating the neocon agenda. With McCain we would have been in a war with both Syria and Iran as a prelude to the war we are involved in now. Obama at least didn’t fall into that neocon trap. Unfortunately that was about the only thing positive about Obama.
