Exit Polling a Vote-By-Mail Election (Pollster Via Politico)

Mark Blumenthal:

In Oregon, where all votes are cast by mail, the survey conducted by the networks is not technically an "exit" poll. They conduct supplemental surveys by telephone in the days leading up to the election in many states with significant early voting (such as North Carolina, Texas and California). They ask the same questions by telephone that voters get on "exit" poll questionnaires administered at polling places. In Oregon, however, all interviews have been done by telephone.

That's fine as far as it goes, but it doesn't answer the question of whether or not exit polling by telephone (potentially weeks AFTER a voter's mail-in ballot was sent in) gives skewed results.
