Even in the bizarro world of current Republican politics, some things defy explanation. How is it, in particular, that Congressional Rs, especially (but not only) those in the House of Representatives, so blatantly line up against the middle class (offering phony explanations)? It's not the only time they've been so unabashed in their crass defense of tax cuts for the wealthy at the expense of providing for the needs of everyone else.
Some absolute partisans might take exception, evidence to the contrary notwithstanding, to #6. The others, though, in all seriousness, must be part of it. It's like I've been saying for years: a dumbed-down electorate, fed misinformation constantly by the right-wing scream machine, lied to until it sounds like truth, whose hatreds and paranoia are played like a harp (what more self-pitying group is there than teabaggers?), are perfectly created to accept and/or ignore whatever their manipulators do.
