Yeah, and LS hasn’t been right about a lot of elections either. Do not put your faith in these guys. They have been so wrong so many times.
I look at the polls for trends, too. However, I don't have the resources, time, or desire, to deep-dive into cross-referencing voter registrations, precinct-level turnout statistics, and year-over-year changes in party identification.
That said, no matter what one thinks of the turnout trend data (not poll data) analysis, I think we can all agree that the Republicans have historically had an awful ground game. Their Get-Out-The-Vote efforts are non-existent; their selection of candidates is based more on fealty to leadership than experience, competence and voter appeal; they have no coordinate party messaging; and the outspoken members of both Congressional chambers spend more time undermining each other's positions at the expense of a consistent election platform.
It's easy to see how poll and trend analysts can be wrong on Election Day. Republicans simply aren't in it to win it.
