WASHINGTON – In the early hours of election night on Tuesday, a consensus began to take hold that the vaunted Democratic blue wave that had been talked about all year was failing to materialize. Now, with a handful of races still to be called, it's clear that an anti-President Donald Trump force hit the country with considerable, if uneven, strength.
Democrats appear poised to pick up 35 to 40 seats in the House once the last races are tallied, according to strategists in both parties. That would represent the biggest Democratic gain in the House since the post-Watergate election of 1974, when the party picked up 49 seats three months after Richard Nixon resigned the presidency.
Republicans will gain seats in the Senate, but with races in Florida and Arizona still to be called, their pre-election majority of 51 seats will end up as low as 52 or as high as 54. Meanwhile, Democrats gained at least seven governorships, recouping in part losses sustained in 2010 and 2014, and picked up hundreds of state legislative seats, where they had suffered a virtual wipeout in the previous two midterm elections.
The Democrats' gains this week are still far short of what Republicans accomplished in their historic victories of 1994 and 2010. But they would eclipse the number of seats Democrats gained in 2006, the last time the party recaptured control of the House, as well as the 26-seat gain in 1982, when the national unemployment rate was at 10 percent. This year, the election took place with the unemployment rate at just 3.7 percent.
Day by day, the outlook for Democrats in the House has improved. At the offices of the Democratic Congressional Campaign Committee, already-high spirits rose all week as more races fell into the party's column. One joke that has been making the rounds there goes like this: "This is actually turning out to be more of a Hanukkah than a Christmas election," meaning day after day of gifts, rather than just one.
This was always an election that would test the strength of the economy, which favored the president's party, versus the president's low approval ratings, which along with the record of past midterm elections, pointed to Democratic gains. In the end, history and presidential approval combined to give Democrats control of the House by what appears to be a comfortable margin.
The Democratic wave hit hardest in suburban districts, many of them traditional Republican territory, where college-educated voters — particularly women — dissatisfied with the president backed Democratic challengers. Ronald Brownstein of the Atlantic and CNN, who has closely tracked these changes over many elections, noted in a postelection article that, before the election, two-thirds of Republicans represented congressional districts where the percentage of the population with college degrees was below the national average. After the election, he estimated, more than three-quarters of GOP House members now will represent such districts.
Democrats flipped about two-thirds of the competitive districts won by both Hillary Clinton in 2016 and Barack Obama in 2012 or by Clinton in 2016 and Mitt Romney in 2012. They also picked up one-third of districts won by Trump in 2016 and Obama in 2012. In districts where both Trump and Romney had won in the previous two elections, Democrats gained about a quarter of the competitive seats.
