Since we dont have a copy of the quote for the Local Insurance Co that was the alternative to the insurance co they did vote in (yeah, I did just call AMA an insurance co again

nyeh! ), we really cant say what the are missing out on. But we can speculate that if it were some company like alstate, would that coverage be denied in certain member vs member claims as the exclusion ama insurance has... as pondered by SoCalGG.
We cannot say for certain the benefits of the policy we havent seen. We dont even know if there actually was a quote given, or if the membership was bamboozled into voting prior to even getting a competitive bid.
edit: horrible typing... just horrible
