I don't remember whether I posted that or not, but it certainly sounds like something I would say... and therefore, sounds correct.Am I misremembering, or did you say that if polls showed the race tightening the actual result would probably be more lopsided as the appearance of a tight race would drive turnout (which generally speaking helps Hillary)?
However, I do remember saying that it could actually work the opposite way... If the polls are showing a Hillary blowout, it could serve to discourage Trump voters, by causing them to stay home in despair... my theory was that blowout predictions depress turnout overall, but probably slightly more among the side that is expected to lose, because its fun to go out and triumphantly vote for the winner (ie., bandwagon effect), whereas standing in line for an hour to vote for a lost cause is sadtimes.
Also, increased turnout overall might help Hillary, but increased Republican turnout certainly helps the Republican Senate candidates... another thing to keep in mind.
