How can they project MD when no precincts have reported?

Does anyone know? Don't get me wrong. I believe it. Just curious how. Especially when we've seen exit polls be really wrong.

1. Early voting totals with a wide enough margin?

2. Early voting and exit polls.

This happens every election cycle. When they know its a blowout, they call it immediately. They may not know if she got 51% or 70%, but they know she won.

3. Because the spread in the exits was so wide

Projections can always be retracted. It's just a safe bet.

4. Exit polling is pretty exact

That and other things like the early vote as a trend.

5. Overwhelming exit poll data...

6. I believe they're holding the precinct results for the state because..

some polling stations are remaining open until 9PM, to adjust for some late openings. So, they have nearly all of the pres primary results, but cannot yet show them.

7. More than 190,000 Democrats voted early in Maryland.

I'm sure those results had a lot to do with the call.
