It's going to be really boring tomorrow night. Either Biden obviously cruises early on and it's called by midnight, or it's close and the networks won't call any swing states until 3 in the morning (and even then it will be the not-really-swing-states like Texas and Georgia, probably Ohio and Iowa, maybe Florida). Then they do a whole morning of endless back and forth until they slowly start to make actual calls around 10am-noon.

If Trump wins big on election day voting and the mail-in votes are slow to count, don't be surpised if the networks don't display ANY results, not even preliminary totals, for some states. Pennsylvania this will almost definitely be the case, maybe a bit less so in Michigan, Wisconsin, Arizona, and North Carolina. You might not see a single voting result for Pennsylvania until noon on Wednesday (or later) because CNN will want to "avoid encouraging misinformation by providing non-representative results before a more accurate count is available"
