Romney was a very weak candidate who failed to inspire and was not perceptibly different ideologically from Obama. And that “47%” remark was devastating, the exact equivalent of Hillary’s “deplorables”. As soon as I heard him say that, I thought It’s over. He just lost the election. Amazing that he did as well as he did, being absolutely NOTHING like Trump!!!
The impact of the 47% remark is fiction. Obama won as all democrats win, but especially him, with a high minority vote. Some conservatives stayed home on Romney. If Trump loses they will have plenty of fictions as to why.
