Nate Silver: “Democratic candidates for the House in 2018 received almost as many votes as President Trump in 2016”, with charts! This is unprecedented. But is it a wave? “Of course it was.”
How big? Nate Silver: Personally, I’d rank the 2018 wave a tick behind both 1994, which represented a historic shift after years of Democratic dominance of the House, and 2010, which reflected an especially ferocious shift against then-President Barack Obama after he’d been elected in a landslide two years earlier. But I’d put 2018 a bit ahead of most other modern wave elections, such as 2006 and 1982. Your mileage may vary.
In another important respect, however, the 2018 wave was indisputably unlike any other in recent midterm history: It came with exceptionally high turnout. Trump’s Base Isn’t Enough | FiveThirtyEight
