I quite agree with what you have just said. In my terms, I would say that there has to be a link between the voter and the elected representative and the link must even be quite close. Today, the link is quite loose. Who calls their MP or goes to see him or her? When and how do MPs manage to reach not only the voters, but the general public? There are various activities, agreed, but there is some disillusionment with politics. In my opinion, it is a societal problem, not just a political one.
That said, strategic voting quite often happens in reaction to something. People are fed up with the government. People do not agree with this decision or that decision. People then vote strategically in order to bring about a change. It is not that they vote without motivation; they may be highly motivated. It is just a pure calculation.
There was something else I wanted to say but I have forgotten it.
