According to this Axios story, the SAM Party has a wealthy benefactor, Charles W. Wall.
The story is somewhat misleading when it mentions the SAM Party in connection with the 2018 Connecticut gubernatorial election. SAM Party endorsed an independent candidate, Oz Griebel. Although the story is technically accurate, an ordinary reader might get the impression that SAM was on the Connecticut ballot in 2018, but it was not. Thanks to Political Wire for the link.
