Most pollsters greatly underestimated GOP vote in MT – what happened?

HELENA — As Election Day approached last week, most public polls had declared the big statewide races in Montana – U.S. Senate, U.S. House, governor – to be relatively close, with Republicans perhaps having an edge.

Yet the final outcome showed no such spread: Republicans cruised to easy victories, up and down the ticket, winning every statewide election by at least 10 percentage points and expanding their already considerable majorities in the Legislature.
