Data on the Comey Effect

There is currently a debate about whether or not the Comey letter flipped the election. Nate Cohn makes a convincing argument that the letter had little to no effect. Some time ago I looked at this myself and came to a similar conclusion. If anything, it was the ACA price hike announcement that had the bigger effect. To test out blogdown (thanks Yihui Xie!) I decided to write this post showing the code I used for the simple analysis I performed, hoping to get others to look at the data, point out mistakes, or show me a better way to do what I did.
