New restrictions causing roadblocks for voters with disabilities

Disability advocates say restrictive voting legislation can have adverse effects on people with disabilities and their caretakers.

Don Natzke, who lost his sight at age 12, says still being able to vote has played a pivotal role in his life.

"It's true of all citizens, but certainly for people with disabilities, the people who are making the policies are very important to us," he told ABC News. "For example, what my community chooses to do to have accessible transportation available affects how I'm able to move around my community."

Natzke, who is now retired, grew up in Wisconsin and says the only way he could vote was to appear at a polling place and have someone read, mark and cast the ballot for him.

"But as technology has moved along, we've ended up having the possibility of accessible voting machines and different ways to vote. This is particularly important," he told ABC News.
