I've read it twice but still have no idea what your point is.The reason the system doesn't work is because no effort has been put into it until very recently.
What's needed is change, re focus on what the voting public want.
Not voting or just voting for somebody that won't get into power but is just a protest will be wasted and we will just get more of the same
Who do you think I should vote for or not vote for?
UKIP had a major effect on the UK despite not getting elected, they caused panic due to the share of the vote it got, resulting in the referendum. Rights and wrongs of Brexit aside, this proves that any party can affect the country without getting elected.
The Lib Dems got enough seats to get involved in government, at the top. They wasted the opportunity, but at least they proved that it could be done, and should know better the next time they get in.
A vote for Labour or Tory is a vote for more of the same crap.
