So what went wrong? He was smeared as a racist misogynist. (On popular leftist sources like ‘The View’.). No doubt that hurt his chances in 2012.

One has to wonder what might have been had Romney won in 2012. It may have brought the right further left, and may have changed the Republican nominee in 2016. But that’s not the way things unfolded.
