Question: When they are saying 4% or 10% of the vote is in, they have called it for Trump/Sanders, and they are saying there are tons of people in traffic jams who will be deemed to be in line and can still vote, how can they call it? Won't some folks just go home and not vote if they are told it's a done deal? Wouldn't some or all of the candidates want to know what the margins would have been had everyone voted? Is the media undermining the process?
I'm a political neophyte and don't claim to understand how all this works so I'm just trying to figure it out.
I don't think they vote all night. They shut the polls down.
I get that. But with only a small fraction of the votes counted and the people in lines (which they have extended to include traffic jams on the way to the polls) told they can still vote, it just seems early to call it, and calling it would make those people turn around and go home. I'm sure they can hear it on the radio or friends/family on the cell phone.
I'm not exactly sure how they do it in NH, but I think that after 2000, news outlets are pretty cautious and don't call elections until it is a statistical impossiblility for another candidate to win.
