What makes 1 more plausible than a vast, right-wing conspiracy that 
changes vote counts across the board in every district without 
detection? Seriously?

OK, here are a couple hypotheses to test:

1) Young people are more likely to vote Democratic and are also more 
likely to answer exit polls than older people.

2) People who work 60+ hours a week are more likely to vote Republican 
and are less likely to answer exit polls than people who work fewer than 
60 hours per week.

3) People without jobs are more likely to vote Democratic and are more 
likely to answer exit polls than people with jobs.

There are all sorts of reasons opt-out surveys are less accurate than 
mandatory surveys. These hypotheses may have explanatory power.
