 Sioux Falls, South Dakota Mayor Paul Tenhaken scheduled to speak at a news conference today on the campaign to stop a measure meant to eliminate grocery taxes. If passed in November, IM-28 would repeal what's known as the grocery tax, or the tax on anything sold for human consumption, including non-alcoholic beverages. Mayor Tenhaken opposes IM-28, as he believes it would create a huge gap in the budget and lead to the creation of a state income tax.
