A short introduction for analyzing text with R

There have been 6 official democratic debates so far and more in the future. The debates are long and frankly very boring. The argument for the debates is to introduce America the candidates and understand their policy positions. However, America has a short attention span and with a 3-hour run-time, that’s a lot of time spent watching tv. In total, a person would spend 18 hours watching the debates.

Some of the bars had 0 charges making the tool give a 0% probability of getting caught/charged. If values were 0, then the tool would give the average probability. There are limitations with the bar tool, arrests and warnings were ignored in the analysis due to…

I remember hearing about Bernie Sanders on the summer of 2015. The term democratic-socialist felt like a radically new concept back then and Bernie’s message resonated with me as an 18-year-old democrat who would be able to vote for the first time. I primaried for him and remember feeling satisfied about the 23–21 loss to Hillary.
