- roughly 70% of the electorate vote
- get 40% of the vote and you have a majority
- therefore your policies only have to please 28% of voters (doesn't matter what non voters think because they don't vote therefore don't count)
In other words the Tories don't have to be "evil" to do things perceived as evil, they're just playing the system the way it has to be played if they want to keep winning.
