Tuesday was National Voter Registration Day in the United States. And two related hashtags were popular on Twitter. The social networking service publicized #iRegistered. The service did something special for users who noted U.S. voter registration and used #iRegistered. Twitter included an Uncle Sam-like hat emoji with the user’s tweet. The hashtag #NationalVoterRegistrationDay was also trending. The U.S. elections are on November 8. The leading candidates for president are businessman Donald Trump and former Secretary of State Hillary Clinton. American voters will also elect a new U.S. Congress and local government representatives. In some areas, voters can express support or dislike for gun control, marijuana use, taxes or other issues.
