I really like Romney's characterization of Obama's election strategy (and the Democrats' in general).
The presumptive GOP presidential nominee accused the president of running a dirty and petty campaign. "He demonizes some. He panders to others," Romney said. "His campaign strategy is to smash America apart and then cobble together 51 percent of the pieces."
The Democrats thrive on identity- and group-base politics. This group versus that group. It is intentionally divisive and it attracts votes by pitting groups against each other.
There's no doubt that individuals in different groups often have different political agendas, but I think the goal should be for the federal government to operate in the zones of commonality. This would mean that the government would be much smaller, but that each program could be designed to achieve 70%+ support from the public. As it is now, very few government programs even get a majority of support.
