I present these 8 visualizations without much comment. Each one represents the bill titles sponsored or enacted by the party and district wealth of the politician who sponsored it. The bigger the word, the more often it was included in bill titles.
Bubbles with only black words are the words that were common between the rich and poor districts. Green words are those bills that were most often used by poor districts, while orange words are those used by rich districts. The first four images describe all 6,000+ bills sponsored in Congress between 2013 and 2014. The last four images describe only those bills that successfully became laws, of which there were only a few hundred. Democrats were the minority party in this time period, so they not particularly successful.
Compare and contrast these bills. Politicians from poor districts talk more about land, politicians from rich districts talk more about ideas. What do you see?
