There shouldn’t be much question about whether 2018 was a wave election. Of course it was a wave. You could endlessly debate the wave’s magnitude, depending on how much you focus on the number of votes versus the number of seats, the House versus the Senate versus governorships, and so forth. 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. Turnout is currently estimated at 116 million voters, or 49.4 percent of the voting-eligible population. That’s an astounding number; only 83 million people voted in 2014, by contrast.
This high turnout makes for some rather unusual accomplishments. For instance, Democratic candidates for the House will receive almost as many votes this year as the 63 million that President Trump received in 2016, when he won the Electoral College (but lost the popular vote). As of Tuesday midday, Democratic House candidates had received 58.9 million votes, according to the latest tally by David Wasserman of the Cook Political Report. However, 1.6 million ballots remain to be counted in California, and those are likely to be extremely Democratic. Other states also have more ballots to count, and they’re often provisional ballots that tend to lean Democratic. In 2016, Democratic candidates for the House added about 4 million votes from this point in the vote count to their final numbers. So this year, an eventual total of anywhere between 60 million and 63 million Democratic votes wouldn’t be too surprising.
