It was worse than just not tapping into, they deliberately pushed conservatives away. Acted as though they did not need conservatives to get Romney elected.
They also could have let Ron Paul speak for 20 minutes or so. Ron Paul does have a following made up of the young hipsters that could have given Romney 500,000 to a million more votes and take that same number of votes away from Obama.
It is unbelieveable how bad a campaign they ran.
