The Mexican American Legal Defense and Educational Fund - MALDEF wants a big change in the way commissioners in Yakima County are elected. They say the current system isn't fair to Latinos. The group sent a letter to the county recently saying they have 30 days to respond or legal action will be taken. The change they want? The group wants the county to change its at-large general election system to a single-district system. It's the second letter demanding change. The first came back in January when OneAmerica sent a letter demanding the same changes while threatening legal action.
