Can Anyone Stop Trump in the Race for the Republican Nomination?

As the race for the Republican nomination slowly drags us towards the scary place that is Donald Drumpf, I thought I would take a look at how the candidates have trended in the opinion polls. This post was inspired by this viz from FiveThirtyEight. They used a trellis chart to show all of the candidates and I’ve been wanting to learn how to build these charts.

Big shout out to Graeme Wiggins for helping me make my trellis calculations much simpler and dynamic so they resize based on the number of candidates. I’ll create a video for how to create these charts in a future Tableau Tip Tuesday. This was quite tricky to build.

The FiveThirtyEight viz is really good, but in my version I wanted to include more:

  1. All of the polls and an option to filter to a specific poll
  2. Choose between the average of the polls or a 2 week moving average
  3. Filter out the candidates that are no longer in the race
  4. An additional view that allows you to compare polls
