How terrible Romney was as a candidate depends on the degree of voter fraud the Demonrats got away with. Some think it was enough to steal the election. I don’t think that but it would have been quite a bit closer without it, the winner-take-all electoral college votes being affected by a relatively small number of votes in key states like Ohio.
Romney ending up losing by 5 million votes (and 166K in Ohio). This in spite of facing one of the worst presidents in the last 100 years, who has buried the country in debt, and saddled us with european levels of unemployment. Romney lacked passion, vision, and human connection. I’m sure there was plenty of voter fraud, but this wasn’t close enough to matter.
