I'm not doing them a disservice at all. Most people don't discuss politics at all, maybe once every few years when an election comes round. Most people vote along tribal lines because they have always voted that way and don't give that much thought to finer details. Most people do not delve into the specifics of manifestos and so on. So in the end it comes down to maybe a couple of key policies people like the sound of and whether they person is likeable or not.
