In the GOP debate, when Cruz compared the Hillary/Sanders debate to, "a debate between the Bolsheviks and the Mensheviks," I assume many of his listeners didn't understand that it was a clever criticism or why. I like Cruz, and he's my first choice by a huge margin, but he needs to use more one-syllable words and remember his audience.
A most excellent point!!! Before I got smart and switched to a Chemistry major, I was briefly a Political Science major. So I fully understood, and appreciated, Cruz's Bolshevik/Menshevik comment.
But to the average voter, Cruz sounded like some sort of wonky goof. And that's not how you get votes.
