Penny Burt: Sarah Palin is news...she is on the stump for Trump. She speaks for and to a large minority of like-minded Americans. Her "word salad" is all slogans, cliches and buzzwords strung together...but it all makes sense to her audience, which pridefully shares her willful and profound ignorance. Don't forget, she is in the right-wing religion business. She believes in evil spirits and has explicitly stated her messiah is coming back from the dead in her lifetime. This appeals to those "in-waiting." She shares with Trump---and with many Americans---the notion that facts, logic, evidence or contradicting previously uttered statements doesn't matter. This appeals to the intellectually fearful...and the intellectually lazy. The guttural grunt as political rhetoric. Political reality...and "news."
