Senator Chuck Grassley is an old Iowa farmer, and he looks and sounds like it, even with a $1,200 three-piece suit on. Not that there’s anything wrong with being an Iowa farmer, but Senator Ted Cruz is obviously more erudite and the smarter of the two.
Grassley was smart like a fox wanting Cruz to present this type of bill to the public.
For the reasons you mentioned and more.
As a student at Harvard Law, Professor Alan Dershowitz said, “Cruz was off-the-charts brilliant.” Cruz was also the first Hispanic to ever clerk for a Chief Justice of the Supreme Court (William Rehnquist). I guarantee, you could easily plop Dana Milbanks' brain into one of Cruz's testicle sacs and shake it around.
