Tech giants Google and Twitter have teamed with the Associated Press to launch AP Election Buzz, a tool for tracking online activity during the election.

Powered by Google Trends and Twitter, the tool’s charts show Google search interest in political terms, and election-related conversation on Twitter. The Google political index measures search interest in a list of 2016 election topics, such as presidential candidates, policy issues and current events. Twitter election conversation analyzes tweets containing data such as candidate names, campaign hashtags and other election-related terms. Both charts use Iowa caucus day on Feb.1 as a baseline.

"Spikes typically coincide with political events, such as debates, primaries and caucuses, though they may occur at different times on Google and Twitter, in part because the measurements differ," explained AP. “The Twitter numbers measure what people are saying online, while Google search data reflect what people want to find or learn about.”

Citing Google Trends data, the tool reports that Republican presidential hopeful Donald Trump accounted for 59.3 percent of search interest in the past 24 hours, ahead of his Democratic counterparts Bernie Sanders and Hillary Clinton with 13.3 percent and 10.4 percent, respectively. Trump was also the main driver of conversation on Twitter, accounting for 58.4 percent of conversation, compared to Sanders’ 14.2 percent and Clinton’s 12.8 percent.

The most mentioned issues on Twitter in the past 24 hours are energy and the environment, national security and foreign affairs, which took 19.5 percent, 16.9 percent and 13.7 percent of conversation, respectively.
