It's difficult to treat a candidate-based election or a Parliament-based election as a referendum on a specific issue. Typically, in one of those elections, you're talking about a basket of issues. Some people when they go to the polls are really worried about the economy. Some may be really worried about whether a particular factory in their town will stay open or closed. Others might be worried about children, or the elderly, or things of that nature. It's very difficult to take an election result and narrow it down to a single topic.
Does that answer your question?
