My father-in-law had the reading comprehension of a middle school student. He couldn’t do algebra if he had a gun to his head. But when it comes to ‘farm’ math, taxes, etc., he’s a damn whiz. He also keeps himself very informed on current political issues and votes according. He would probably be considered a rube by some, but he has every right in the world to vote. And I wouldn’t have it any other way.
