The letter is meant as a political show of force for Kamala Harris in a tight race with Donald Trump. The first presidential debate is less than a week away.
The reason for the long list and the short letter is because the letter itself was not written to convince the general public to vote for Harris.
Instead, its purpose is to serve as a well-timed political show of force for Harris, who is locked in a very tight race, with the first presidential debate just four days away.
Who does this intend to convince?
big corporate donors?
