FiveThirtyEight: The Democrats’ wave could turn into a flood

So Democrats are up a lot. A lot a lot. But how might a lead this big manifest itself in 2018? First, Democrats are probably favorites to win the House. Their current advantage is larger than the lead Republicans had at this point in the 1994 cycle, the lead Democrats held at this point in the 2006 cycle or the lead Republicans had at this point in the 2010 cycle. Those were all years when the minority party won control of the House. And a 12 percentage point Democratic advantage in the national House vote come next November would likely be more than enough for the House to flip again. I’ve previously calculated that the Democrats need to win the national House vote by 5.5 to 8 points to win the House.
