Funny that Noem wasn’t mentioned;
The most conservative Republicans in Congress tend to speak at the lowest grade level, according to an analysis by the Sunlight Foundation.
The analysis found that the more conservative a Republican was, the lower his or her speech level tended to be. But same is also partially true for lawmakers on the opposite side of the political spectrum. More progressive Democrats in Congress also tend to speak at a lower grade level. However, the decline in speech complexity is less pronounced for Democrats than it is for Republicans.
