A clear distinction which some people refuse to get . . .
Actually, some people -- like you -- refuse to get that motivation has zero impact on results. The results are the same regardless of the intention of the politician who advances the leftist agenda, as Romney HAS and DOES on abortion, government-run health care, the environmentalist power grab hoax, minimum wage, the homosexual agenda, judicial appointments, and 2nd Amendment rights.
Some people refuse to get that voting for leftists increases and empowers leftism every time.
