If liberals are more altruistic, then tell me why (as Rush Limbaugh told us today on his show) conservatives on ALL Levels of income give more than liberals do. Conservatives also donate more blood than liberals do. If liberals gave more blood, the supply would go up some 42% (I am quoteing off what I heard of the show today.) Of course, why would America want more liberal blood?
Also, a liberal and a true conservative would obviously govern differently. Therefore, both positions are more than just personalities.
