There are lots of reasons, why one would vote for the way they do (tory) and often fairly uncontroversial.
- Lower taxes
- strong stance against illegal immigration
- Less regulation for the self employed
- more business friendly
- Politics of aspiration
- Competition in education
- Perceived to be more on the 'side' of freedom of speech
I am not saying I agree or support all the above talking points, but I am trying to display a general theme, that surely you can see why a local business man or self-employed builder who can afford to send their kids to a private school would vote conservative, without necessarily being an evil person.
