They played video. They brought graphics. They cited Alexander Hamilton so many times, they may owe royalties to Lin-Manuel Miranda.

The Democratic House impeachment managers, unfolding their case against President Donald J. Trump, were conducting a TV trial without many of the staples of legal drama, particularly witnesses on the stand. Instead, they relied on multimedia, impassioned speeches and repetition, repetition, repetition — all in a presentation of 24 hours over three days.

If the O.J. Simpson trial was a long-running daytime soap, this was democracy in binge mode.

The trial of Mr. Trump, as the TV pundits reminded us before, during and after, was an unusual one, in that much of the jury was assumed to already have a verdict in mind. This meant a different dynamic from the usual televised trial, in which the prosecution is speaking to the jury first and the viewing audience second, if at all.

Instead, Representative Adam B. Schiff of California and his team were effectively speaking to the court of public opinion — home viewers who might bring pressure to bear on certain swing senators, or turn against them at the ballot box — though they had to do so by at least arguing as if the outcome were not a foregone conclusion.
