With just under a year until U.S. Election Day, Twitter is bringing back its Election Labels, which provide information about political candidates — including what office they’re running for and their state and district number. The labels will also have a small ballot box icon to accompany this information. The feature was first launched during the 2018 U.S. midterms, where the labels were seen 100 million times per day by Twitter users in the week before Election Day.

In addition, 13% of U.S. election-related conversations on Twitter included a tweet with an Election Label, the company says.
