I do actually think that their analysis of the General Election gets to much crap -- they overestimated the application of history to this year's primary, but the General Election probably is a lot more predictable. Still, more of a grain of salt there than in the past, too.
Agreed. Silver and co bought in heavily to the Party Decides theory of primaries, despite the small sample size of competitive primaries in the modern era and said primaries having data points that the party establishment does not always decide.
Their coverage of the election has drastically improved since Silver's mea culpa on Trump's primary win.
