The US Presidential Candidates app helps you see the overall sentiment towards the top two candidates in the 2016 US election using Twitter statistics from the last 30 days.

This app measures negative and positive words in tweets directed at or mentioning Hillary Clinton and Donald Trump, and the application uses those words to measure the "public sentiment" quotient of each candidate as viewed by social media. public sentiment is measured by dividing the number of positive words by the combined total of positive and negative words in tweets. You can see which hashtags are being used most frequently, recent tweets, and statistics about the sentiment by candidate or geographic location.
