I am not 100% sure about this, but I don't think there's any record of the results of an advisory vote significantly influencing legislation. '

They exist because of Tim Eyman. Excerpt of the main stuff if you hit the paywall: "The tax-related questions put to voters have been a staple of Washington ballots since 2007, when anti-tax initiative activist Tim Eyman ran and won voter approval for Initiative 960. The campaign’s success means that anytime the Washington Legislature opts to raise taxes, their actions are subject to judgment by voters."

Fortunately advisory notes don't mean anything anyway.

Just wait til Elon's Neuralink is available...

"No exciting referendums or initiatives on the ballot, no Governor or presidential races, and a state where many people have gotten used to the idea it doesn’t matter if they vote, democrats like Murray get auto vote back into office every time."

Maybe this is why the even-year elections initiative is on the ballot...
