I don’t want to go too far out on a limb in terms of any sort of prediction for 2020. In fact, lest you think that the midterms were the first step toward an inevitable one-term Trump presidency, several facts bear repeating: Most incumbent presidents win re-election, and although Democrats had a strong midterm this year, midterm election results aren’t strongly correlated with what happens in the presidential election two years later. Moreover, presidential approval numbers can shift significantly over two years, so while Trump would probably lose an election today on the basis of his approval ratings, his ratings today aren’t strongly predictive of what they’ll be in November 2020.
But presidents such as Reagan, Clinton and Obama, who recovered to win re-election after difficult midterms, didn’t do it without making some adjustments. Both Reagan and Clinton took a more explicitly bipartisan approach after their midterm losses. Obama at least acknowledged the scope of his defeat, owning up to his “shellacking” after 2010, although an initially bipartisan tone in 2011 had given way to a more combative approach by 2012. All three presidents also benefited from recovering economies — and although the economy is very strong now, there is arguably more downside than upside for Trump (voters have high expectations, but growth is more likely than not to slow a bit).
Trump’s political instincts, as strong as they are in certain ways, may also be miscalibrated. Trump would hate to acknowledge it, but he got most of the breaks in the 2016 election. He ran against a highly unpopular opponent in Clinton and benefited from the Comey letter in the campaign’s final days. He won the Electoral College despite losing the popular vote — an advantage that may or may not carry over to 2020, depending on whether voters in the Midwest are willing to give him the benefit of the doubt again. Meanwhile, this year’s midterms — as well as the various congressional special elections that were contested this year and last year — were fought largely on red turf, especially in the Senate, where Trump may well have helped Republican candidates in states such as Indiana and North Dakota. The Republican play-to-the-base strategy was a disaster in the elections in Virginia in 2017 and in most swing states and suburban congressional districts this year, however.
At the least, odds are that Trump needs a course-correction, and it’s anyone’s guess as to whether he’ll be willing to take one. While there’s some speculation that Trump could move in a more bipartisan direction, that hasn’t really been apparent yet in his actions since the midterms, or at least not on a consistent basis. Instead, he’s spent the first fortnight after the midterms firing his attorney general, implying that Democrats were trying to steal elections in Florida, and bragging about how he’d give himself an A-plus rating as president. The next two years will less be a test of Trump’s willpower than one of his dexterity and even his humility — not qualities he’s been known to have in great measure.
