I am pretty sure we will not hear any of the major news networks start to call races until after 8 p.m., even in states whose polls close earlier. I will caveat that statement by saying that if either of the earliest closing states–Indiana or Kentucky–appear to be a blow out, they may call those states. Otherwise, we probably will not hear anything until after polls close in the 8 p.m. states.
That being said, polls start closing in Indiana and Kentucky in an hour.
