On October 7, former New York city Mayor Michael Bloomberg donated $1,250,000 to “Yes on 90”, the chief committee that is advertising in support of the top-two system that is on the November 4 ballot in Oregon.
As previously reported, another billionaire, John Arnold, donated $500,000 on September 17, and another $1,000,000 on October 1, to “Open Primaries”. That committee then gave those donations to the “Yes on 90” committee. Presumably this money will pay for radio, television, newspaper and direct mail advertising in favor of the measure.
Here is a link to the donations to Open Primaries, and here is a link to the donations for Yes on 90. Note also that Bank of America donated $10,000.
