It's the importance of voter interaction, in 140 characters.
After two debates in the Republican primary, voters are beginning to see the importance of head-to-head matchups in deciding who to support. We've found one simple stat that can actually help predict the post-debate polls: the increase in Twitter followers for each candidate.
This goes beyond social media "mentions" and "discussion" and "sentiment" scores — metrics that can be important but are often the echo chamber of people who already support a candidate.
Here's our live tracking for the 10 candidates on the main stage Wednesday. It will update in real time during the two-hour debate. Use this as a way to predict who actually "won" the most new followers — and who will likely rise in the next polls. Refresh this page during the debate to see the chart show the latest numbers.
