One constant in Donald Trump’s 11 years in politics has been his demand for credit for every idea, event, and program. In his telling, no one before him ever was clever enough to conceive of his newest scheme. As he likes to say, “no one’s ever seen" whatever he's currently talking about.
All that is on display again as Republicans, more anxious than excited, plan to gather next week to fulfill the president’s desire to have a midterm convention to showcase his second-term record. When he first proposed it last year, he boasted, “It has never been done before.” He repeated those words in June when he announced the date and location—Sept. 9 and 10 in Dallas.
The only problem is that it has been done before. And it didn’t work out very well, making this an instance when Trump would have been far better served if he had actually talked to Democrats. They’re the only ones with experience at midterm conventions—and the bruises to show for it.
Far from being an idea that sprang from the fertile mind of Trump, midterm conventions were first suggested by Republican National Chairman John Hamilton in the wake of Franklin D. Roosevelt’s 24-point shellacking of GOP nominee Alf Landon in 1936, according to Hamilton College professor Philip Klinkner in his 1994 book, The Losing Parties: Out-Party National Committees, 1956-1993. Twenty years later, Sen. Estes Kefauver championed midterm conventions after Dwight Eisenhower’s 15-point thrashing of the Democratic ticket, which included Kefauver as vice presidential nominee.
Both Hamilton and Kefauver failed to sell the idea. But another 20 years on, a reform-minded Democratic Party, stung by its 23-point clobbering by Richard Nixon in 1972, revived the idea, even managing to stage events in Kansas City in 1974, in Memphis in 1978, and in Philadelphia in 1982.
They did not go well.
“Trump doesn't understand what came before. He just doesn't know history,” said Al From, an adviser in the Jimmy Carter White House and a loud voice for moderating the Democratic Party after Ronald Reagan’s two victories. From attended the Democratic midterm convention in 1982, which, he said, along with the editions in 1974 and 1978, “didn’t work out very well.”
That understates how disastrous the gathering was in 1978. In that year, like this one, it was the party that won the most recent presidential election that proposed the gathering—although, in a key difference, the Democrats assembled weeks after the midterms.
Carter gave a speech on the opening night to a tepid reception and then returned to the White House. He was not there on the concluding night when Sen. Edward Kennedy gave one of the most rousing speeches of his career, urging his party to “sail against the wind,” signaling he would be a likely primary opponent to Carter in two years.
It is an item of faith today that Carter was deeply unpopular at the time of that convention. The numbers tell a different story, though. While his approval, as measured by Gallup, was only 39 percent in August 1978, it was at 49 percent by the November election and at 51 percent when the convention started on Dec. 7.
The contrast with Trump’s current unpopularity is sharp. The University of Massachusetts poll conducted in late August showed 64 percent disapproving of his performance and only 32 percent approving. That is slightly worse for the president than other current polls—42 percent approval in Quantus Insights, 36 percent in YouGov/The Economist, and 33 percent in Reuters/Ipsos.
Democrats killed off their midterm conventions in 1985 when new party chairman Paul Kirk declared them “places for mischief” and a waste of party time, money, and energy.
The abiding lesson from the three mini-conventions was that they could prove to be boons to future candidates, but debilitating for incumbents. Jimmy Carter, the loser in the 1978 event, had been the star in the 1974 convention, laying the groundwork for his later campaign. Similarly, Bill Clinton effectively used the meeting in 1978, and Walter Mondale was a star in 1982. Indeed, as The Washington Post put it, Kirk said the conventions mostly just "kick off speculation about presidential contenders when Democrats should be focusing on electing senators, House members and governors."
