Almost two weeks on from Mitt Romney's crushing loss to Barack Obama, the memory of his gracious and widely praised concession speech is fading fast.Since then the defeated candidate has made series of ill-received remarks blaming his loss on President Obama's 'gifts' to African Americans and Latino voters - putting him at odds with party leaders.And as Republicans struggle to comprehend the scale of their defeat, the former Massachusetts governor is said to have become persona non grata to the party at large - a remarkable fall from grace for a man who expected to be president-elect right now.
