Why isn't Seltzer polling IA?

[True Federalist (진정한 연방 주의자)]

They have enuf paid work that they aren't about to do a freebie. Besides, it's almost time for the Des Moines Register's annual Iowa Poll, so likely that and one just before the election will be all the Selzer we get this year for the general election.  Other than not doing a GE poll at caucus time, that's the same as in 2012.
