Remember the “big lie”? In 2020, Donald Trump lost the presidential election so Republicans just brazenly lied and insisted he won.

In 2024, we have a new post-election lie from the Republican party. Trump didn’t just win, they say, but he won big. He won a landslide. He won an historic mandate for his ‘Maga’ agenda.

And it was Trump himself, of course, on election night, who was the first to push this grandiose and self-serving falsehood, calling his win “a political victory that our country has never seen before” and claiming “America has given us an unprecedented and powerful mandate”.

Republican politicians, masters of message discipline, quickly followed suit. Representative Elise Stefanik called her win a “historic landslide” while Senator John Barroso called Trump’s a “huge landslide”. “On November 5 voters decisively elected Donald Trump with a mandate for sweeping change, and they deserve to get it,” wrote Doge co-heads Elon Musk and Vivek Ramaswamy in the Wall Street Journal on 20 November.

None of this is true. Yes, Trump won the popular vote and the electoral college. Yes, Republicans won the Senate and the House. But, contrary to both Republican talking points and breathless headlines and hot takes from leading media outlets (“resounding”, “rout”, “runaway win”), there was really nothing at all historic or huge about the margin of victory.

Repeat after me: there was no “landslide”. There was no “blowout”. There was no “sweeping” mandate given to Trump by the electorate. The numbers don’t lie.

First, consider the popular vote. Yes, Trump became the first Republican for two decades to win the popular vote. However, per results from CNN, the Cook Political Report, and the New York Times, he did not win a majority of the vote. Barack Obama did in both 2008 and 2016. Joe Biden did in 2020. But Donald Trump failed to do so in 2024.

And the former president’s margin of victory over Harris is a miniscule 1.6 percentage points, “smaller than that of every winning president since 1888 other than two: John F Kennedy in 1960 and Richard M. Nixon in 1968”, as an analysis in the New York Times noted last month. In fact, in the 55 presidential elections in which the popular vote winner became president, 49 of them were won with a margin bigger than Trump’s in 2024.

We actually know what a landslide in the popular vote looks like: Democrat Lyndon Johnson defeated Republican Barry Goldwater in 1964 by an enormous margin of 22.6 percentage points!

Second, consider the electoral college. Trump won 307 votes, which is 37 more than is needed to secure victory in the electoral college. But it’s still far fewer than Bill Clinton won in 1992 (370) and 1996 (379) and far fewer than Barack Obama won in 2008 (365) and 2012 (332). And it is pretty similar to what Trump himself won in 2016 (304) and what Biden won in 2020 (306). Trump’s margin of victory in the electoral college ranks 44 out of the 60 presidential elections in American history.

We actually know what a a landslide win in the electoral college looks like: Republican Ronald Reagan won re-election with a whopping 525 electoral college votes in 1984!

By the way, did you know that Trump won the crucial Blue Wall states - Michigan, Pennsylvania, and Wisconsin – by 231,000 votes? So if just 116,000 voters across those three swing states – or 0.7% of the total – had switched from Trump to Harris, it is the vice-president who would have won the electoral college … and the presidency!

Third, consider the so-called “coattails” effect, where a presidential candidate’s massive margin of victory also boosts their party’s numbers in Congress. In 2024, Republicans flipped the Senate and held onto the House but Trump still ended up having “limited coattails”, to quote from the New York Times analysis. Of the five battleground states (Arizona, Michigan, Nevada, Wisconsin, and Pennsylvania) which held Senate races in November, the Republican candidate triumphed in only one of them (David McCormick in Pennsylvania, by a narrow 16,000 votes). Democrats held onto the other four.

So where were the Trump coattails in the Senate?

Meanwhile, over in the House of Representatives, Republicans held onto control of the chamber with the aid of an extremely partisan and anti-democratic gerrymander in North Carolina, signed off by a conservative-majority state supreme court. They are on course for what CNN election analyst Harry Enten is calling a “record small majority”.

So where were the Trump coattails in the House?

And yet, the president-elect and his army of Republican sycophants cannot stop bragging about the landslide that wasn’t. You almost have to admire their chutzpah.

But there is also method to their meglomania. As political scientist Julia Azaria has observed, when a president and a party claim a sweeping mandate it has “historically been connected to unprecedented expansions of presidential power” and can become a way “to give an unchecked executive the veneer of following the popular will”.

Trump, the 49.9% president, doesn’t represent the popular will. Yes, he won the election fair and square, and won the popular vote for the first time, but if we are to prevent him from expanding his power in the Oval Office we must resist this new Republican election lie. We must not allow him to pretend that he has some sort of special “mandate” for controversial policies and personnel.

Repeat after me: there was nothing unique or unprecedented about the election result last month. Republicans may feel they won a huge victory over the Democrats. And Trump may feel his election win was historic. But, to borrow a line from the right, the facts don’t care about their feelings.
