They may pay lip service occassionally to the right thing: "Let's get bin Laden" or "Deficit spending is bad.", but they always oppose anything that would actually lead to resolutions of those things.
I’ll assume this wasn’t a rhetorical question and give you an answer.
It only appears that the Democrats get everything wrong becuase you are incorrectly assuming that their goal with any particular statement or policy is as they say it is.
Stop believing that they mean ANYTHING they say. Stop beleiving (if you do) that there are ANY honest liberals, they dont exist. Stop giving them the “benefit of the doubt”, they are NOT misguided. They are evil, because they do know better (whether they’ll admit it or not). Anyone who will look you in the face and deny reality, is actively trying to put one over on you, therefor is evil.
There is ample evidence throughout the history of this and other countries that their beliefs are flat out contradictory to the “freedom” that they pay lip service to.
