On June 30, the chair of the Maine Democratic Party filed a lawsuit in state court, to remove the only independent candidate for U.S. Senate from the November ballot. The case is Knutson v Department of the Secretary of State, Kennebec County. The Secretary of State had determined that the candidate, Herb Hoffman, has 4,000 valid signatures. The lawsuit argues that the Secretary of State is mistaken. The specific dispute includes whether a signature is valid if the signer gives a Post Office Box address, and whether certain signatures were properly witnessed.
Hoffman is a former Democrat who supported Dennis Kucinich for president. Hoffman became disillusioned with the Democratic Party, partly because of how Kucinich was treated, and partly he disagrees with the stances of the Democratic nominee for U.S. Senate on foreign policy. If Hoffman is removed from the ballot, there will only be two choices remaining on the Maine ballot in November for U.S. Senate.
