The progressive left in this country, like it or not, has little or no political weight--this results in a "Tinkerbell" mindset, to the effect that if you don't loudly shout "I believe, I believe, I believe" then the little, flittering glimmer of leftist joy and hope will instantly fade away and die--

Ironically, this gives the generally progressive population the impression that the "progressive left" are uncompromising lock-step ideologues who are too inflexible to be taken seriously--This also means that politicians who actually share progressive leftist visions are careful to avoid saying or doing anything that would connect them with the "progressive left"--

America can be only be moved to the left exactly the same way that it was move to the right--by rhetorically embracing the "American Dream" and then quietly shifting policy--
