While it should not be a slow process of education it has become a very slow process of education to wake average U.S. citizens and inform them regarding the average leftist politcian's true ideological goals.
I think that the ultra slow process is because the Left essentially controls the educational system, the entertainment system (making televisions shows and movies) and the mainstream media outlets. Thus people have to compare out come to promises and learn to filter leftist SPIN.
As for Europe and elsewhere . . . they are hopeless because U.S. politics is a spectator sport to them rather than something that affects them in real time . . . and so they have no motivation to dig out the real truth about anything.
