I don't know how early it was proposed for a tax increase on businesses that could afford it to help the Oregon economy (see here). I would guess that billions were spent on advertizing for or against. Unfortunately, those against the proposal (the large companies, most I would suspect were oligopolies) had more to spend. Both represented themselves as "small business owners" - the ones who actually were small business owners spoke from the heart. They would give the reasons the economy would be changed if the voter voted "YES"
The large companies with money hired actors and actresses who read well and evidently were better at acting than say the geriatrics who "help me, I've fallen, and I can't get up" except THEY WERE READING - NOTHING WAS FROM THE HEART - they'd be ever so smug about it, using the name WILCO - trying to deceive the public familiar with Winco perhaps (for example) and thinking they recognized the name. Their deceitful ads worked. The bill did not pass. The small businesses suffer as a result. But glory be to the oligopolies who were able to keep themselves from being taxed. They must be so proud.
