In a constituency where hypocrisy is an existential feature thereof, being dumbed down, clueless and gullible is a must have component toward being hypocritical. So as far as the grass roots Republican party goer's are concerned, it's all a neat tidy package that got hand delivered to Trump who then proceeded to make them even dumber still thus spiraling them into endlessly being more comfortable with their hypocrisy.
When their world is built on a foundation of lies smothered in propaganda produced and provided by those very wealthy folks who run the United Shadow States of America, being contradictory and projective is their only defense against the truth and facts about their party's agenda and it surely ain't about securing the southern border, and it ain't about putting the gays and tranny's in their place, it's not about banning books, nor is it about family values and fiscal conservancy or about the racists, nationalists, supremacists and religious zealots that are pushing their own agendas from within that party's infrastructure.
It's all about seizing and maintaining the power and influence that the nation's unelected power brokers can wield against the middle class and the poor in order to keep themselves exactly where they are now.
