The actual idea of voting implies a transfer of power to the politicians.
democracy or this collectivist sham transfers power to one set of CAREER politicians or another and the INDIVIDUAL is left powerless.
While we have freedom to choose certain vital courses of action, like where or how we work, whom we choose to marry etc, the most important liberty of all is the right to opt out – not to be forced to finance a certain policy, not to subscribe to a certain policy.
It is this right or liberty which the current party system takes away. See my website www.camrecon.demon.co.uk . Liberty is also threatened because party politicians are not free to protect our liberties, which, as Lord Hailsham says on my website was their traditional role, and as they are part of the Executive and looking for promotion do as they are told too often.
The party system comprises a "package" of policies which you accept or reject ENTIRELY. It is this which destroys individual liberty, which is not just about money it is about social choices which are forced upon ius by anti-discriminatory legislation. some freedom
Unless we separate the Executive from the Commons once again pretence at freedom is just a whitewash.
