The electoral college is how we tabulate results, not popular voting. Until you cons can regain an electoral college majority you will not win.
Think of this election as a free market. The buyers looked at Romney's wares (the GOP platform) and Obama's wares and decided on buying Obama. Time to make changes in your party product or the free market will keep rejecting what you're selling.
Your job is not to get 2 miilion more votes. It's to regain Ohio and Florida and Pennsylvania and Nevada and Wisconsin and the dozen swing states you lost.
