First Polls of the Night Close

The first polls have closed in Tuesday's midterm elections. Polls in most of Indiana and Kentucky closed at 6pm Eastern time, CNN reports, but parts of both states are in the Central time zone, so it will be a while before full results are in. Here are some key races to watch as those and other early results filter in. By Tuesday afternoon, the nonpartisan Election Protection hotline had received 17,500 calls from voters experiencing problems, up from 10,000 in the morning, the AP reports. (There were reports of malfunctioning machines and long lines as voting began.)
