Polls in Indiana are open from 6am to 6pm local time. Since part of the state is in Eastern Time and part is in Central Time, polls close at 6pm ET in most of the state, but 7pm ET in the rest of it. The networks won’t release the exit poll toplines or call the state until 7pm ET.
At 5pm, the networks will be given access to the early exit poll numbers. So some time between about 5:10 and 5:30pm or so, we’ll start getting news reports from them about things like what percentage of the voters are Independents, what the top issues on voters’ minds are, etc. But they’ll withhold the topline numbers (who is winning the exit poll) until all the polls have closed in the state.
