The "main" parties know that the electorate will just seesaw back and forth over the years as there was no real viable alternative. UKIP is making them think a bit differently because they are gaining popular votes around the country, derailing the Gravy Train that career politicians rely on.

After all, the main purpose of any politician is to get elected. After that, Party politics mean they don't have to stick to any pre-election promises at all.
