There is then a wider political question.
The demolition of the duopoly in Westminster politics has been talked of before.
Think the birth of the Social Democratic Party, or SDP, in 1981.
There was the coalition government of the Conservatives and Liberal Democrats between 2010 and 2015.
In the 2019 European Parliament elections, the Conservatives and Labour only managed to cobble together 23% of the vote between them.
And yet before and after each of these moments, one of the Westminster big two went on to win the next general election, often handsomely.
Indeed, months after those European elections, the Conservatives won a big majority at Westminster.
Two years earlier, the big two in the Commons swept up 82.4% of the vote combined.
So it is wise to bring perspective to this discussion, rather than breathlessness.
But it is wise, too, to acknowledge the sheer scale of this breakthrough by Reform UK.
They went into these elections with the challenge of proving that they could match in votes what the opinion polls had suggested they could.
They comfortably exceeded that high expectation which is why this is a profound moment in our contemporary politics.
Senior Reform figures believe the primary driving motivation behind their surge was that most powerful of human emotions: betrayal.
Betrayal, they argue, from both of Westminster’s big beasts.
So what happens next?
Well, the pyrotechnics of modern politics continue, and not just in the field used by Reform UK for their celebratory party.
And a final thought: if English politics feels splintered and noisy, remember Scotland and Wales and Northern Ireland too.
Next year, there are elections to the Scottish and Welsh parliaments.
Reform are pretty excited about those elections as well.
The Scottish National Party, Plaid Cymru and others will, of course, be in the mix then too.
The widening cacophony of political voices demanding our attention and endorsement could get louder yet.
