The Chamber of Commerce is not a government organization. They are certainly a powerful lobby group, but give the current administrations history of completely ignoring views that aren't in alignment with their own, this certainly isn't a silver bullet.
The good news is that this is just another item that Senators who want to take our side can use as a tool to support their opposition to S373. In your calls and meetings with your Senators, make sure to mention the views of the Chamber of Commerce.
I'll have updated talking points for meetings and phone calls that incorporate the views of the Chamber up on www.nosnakeban.com by the end of the day.
