The difference between Republicans and Democrats is effective mental age. Republicans behave and think like 6 year olds, totally self centered and 100% dependent on others to save them from their own ignorance. When presented with facts, they lie to avoid taking responsibility for their own actions. I mean, seriously, can they REALLY be too ignorant to see the effects of AGW? Nope, it's the 6 year old response, I'll deny it and force MOM and DAD to fix it. Democrats behave and think like adults, value all life, and understand that lying about a problem or ignoring it doesn't solve it. Democratic politicians still lie, but only with respect to promising action, never denying reality and facts.
In short, Republicans are irresponsible 6 year olds, and Democrats are mom and dad.
