Talking about what went wrong, Romney said they didn't get the turnout from minority voters that they needed and he acknowledged his campaign was outmatched by his opponent's massive organization."I think he had as many as 10 times the number of ground workers, paid staff, that we had, because he could afford them and we couldn't," he said.
Uh, Romney's campaign directly spent over $480 million. I'm pretty sure they could have afforded a better field program than the one they actually built.
The Obama campaign had more ground workers and paid staff because they managed their funds a lot better than Romney did and prioritized their field and data programs higher than Romney's. Mitt squandered a fortune on consultant fees and wildly mis-targeted his media buys, which wasted millions of dollars that could have gone to build a more competent field program.
He also came off as a self-important, dishonest, uncaring jerk, which might have had some impact on his low-dollar fundraising efforts. But either way, he could easily have afforded a better campaign, he just didn't have the skill to build one.
