Republicans are greedy, heartless and cruel.
Think back on the great ideas of the last 50 years. Head Start, Peace Corps, Habitat for Humanity - just to name a few. Every single one of them has been the brainchild of liberals. Liberals aspire to a better world, a world in which real value is placed on human life.
Republicans, by contrast, underfund or eliminate social programs whenever they get the chance. They know that a permanent underclass is needed to sustain their wealth and power. That's why they allow what's known as "dead serf's insurance," where corporations take out secret insurance policies on their empolyees. When the employee dies, the corporation is still making money on them.
