Ransom, you normally get things right, but this time you're way off. Romney didn't lose because of the GOP party - he lost because of two things: media support for Obama and the voters themselves. The media support for Obama was particularly damning as the lamestream media went out of their way to ignore the fiascos and corruption of this regime, unapologetically shilling for Obama.
The second part lies in the selfishness of the voters themselves. People are more interested in the free cell phone or government handout than in realizing that nothing is free. Obama literally bought this election at the cost of American Taxpayers. He not only had a billion dollars from donors, but he had $1.3 trillion each of the past four years.
