Ghost voting, in this context, is when legislators vote for bills on behalf of other members who aren't actually present. I am somewhat embarrassed to say that I never knew about this practice until I watched John Oliver's 2/14/16 show focusing on voter ID laws. That was a while ago, but the recent events involving voting reminded me of this issue and I was curious whether anything had been done to solve this problem. Unfortunately, my research of google results turned up no significant information on recent steps taken by legislative bodies to prevent these practices.
Are there actual examples of steps taken to stop the practice of Ghost voting in any US state legislative body in recent years?
