One of the many things left wing liberals should never comment on for fear their own history will become the topic. Economics, the military and their misuse of the military in conduct of wars, anything to do with morals values standards, balanced budgets with a surplus, following Constitutional law, campaign and voting irregularities, health care, buying votes with ethanol, food prices, starving children, feeding North Korea to deter WMD development....
not much left for them to talk about

Republicans these days are much tarred with the same brush since most are just Democrats in disguise anyway.
