John McCain has criticized his own party's failures and gone against Republican orthodoxy. Has Barack Obama ever gone against his party's line? He "talks a lot about finding ways to move beyond the bloody battlegrounds of the 'culture wars' in America; the urgent need to establish consensus on the emotive issue of abortion," without ever making a concession to pro-lifers. "Politician Obama's support for abortion rights is the most extreme of any Democratic senator... The fact is that a vote for Mr Obama demands uncritical subservience to the irrational, anti-empirical proposition that the past holds no clues about the future, that promise is wholly detached from experience."
