Acquitting Trump would spell grave danger for US democracy | Jonathan Freedland

Failing to convict the former president will send a clear and alarming message: future elections can be overturned by force

Rare is the trial that takes place at the scene of the crime. Rarer still is the trial where the jurors are also witnesses to, if not victims of, that crime. Which means that the case of Donald Trump should be open and shut, a slam-dunk. Because those sitting in judgment saw the consequences of what Trump did on 6 January. They heard it. And, as security footage played during this week's proceedings showed, they ran for their lives because of it.

And yet, most watching the second trial of Trump - only the fourth impeachment in US history - presume that it will end in his acquittal. They expect that fewer than 17 Republican senators will find the former president guilty of inciting an insurrection and so, lacking the required two-thirds majority, the verdict will be not guilty. Barring a late spasm of conscience by the senate Republican leader, Mitch McConnell, Trump will pronounce himself vindicated, the case against him a hoax and he will be free to run again in 2024 - and to loom over his party as its dominant presence at least until then.
