Some of us real conservatives out there would rather see Obama win again than Romney.
Before you stone me for treason, the reason is simple: There is 0% chance a true conservative candidate of the ilk of Reagan or Paul will ever be on the Democrat ticket, but there IS a chance that the Republican Party can be salvaged. If Obama wins again, perhaps the GOP will nominate a real conservative for 2016—say, Rand Paul? America will hate the Democrat Party even more, and we won't have to worry about an incumbent buffoon Romney running the US into the ground.
Since both Obama and Romney will ruin this country, I'd rather have Obama do it so the GOP doesn't look quite as bad.
