President Joe Biden increasingly stops mid-sentence to start over with a new thought, correct himself, or go on a tangent, at a rate twice as frequent as when he was Vice President, according to a Daily Wire analysis of official White House transcripts.

The man who assumed the presidency in January 2021 was not the same speaker who left the vice presidency in January 2017, the analysis of thousands of speeches across 11 years showed. And the man who bumbled through remarks in recent months was not the same one who assumed the presidency just three years ago.

The president’s difficulties keeping his train of thought or speaking clearly are reliably reflected in official transcripts by em dashes, like this: “I sat down — and we were in Great Britain, in England — and I sat down, and I was sitting between as he used to go, ‘Boris!’ The former prime minister was an interesting guy. And — (laughter) — no, he’s not a bad guy. But — and Macron and — and Schmidt [sic] and, you know — I mean, Scholz — what am I talking about?”

This animated chart shows the massive increase in such speech between 2017 and 2021, and in each three-month period of his presidency since. Watch the graphic to see it highlight an example of his rambling speech from each time period every few seconds:

The chart confirms quantifiably, through an objective methodology, the decline in Biden’s cognition that was on display at his June 27 debate against Donald Trump, and suggests that it would be far worse by the end of a second term. It shows that the bumbling manner of speaking is not the result of a lifelong stutter or simply a folksy style, but something that has gotten progressively more pronounced over time, and at this rate could soon make the commander-in-chief difficult to comprehend.

The analysis of rambling speech mirrors the findings of a previous Daily Wire investigation that looked at errors corrected by the White House in transcripts.

That story found that cases where he said the completely wrong words, leading White House staff to strike out his remarks and replace them with what he should have said in brackets, doubled in the 12 months leading up to his disastrous debate performance in June. The staff made 51 corrections to the official transcripts this May alone, up from 33 a year prior, as Biden said things like “I still got 136 [3.6] million people’s debt relieved,” “Today, 720 [270] million Americans,”and “When you muild from the biddle [build from the middle].”
