[rsp1984]

The obvious problem with the 5% rule is that voters who don't like any of the established parties are faced with the decision between voting for something they don't like or most likely throwing away their vote.

As someone who writes algorithms for a living I can think of ~ 100 ways to resolve this bug without limiting the original intent. You don't have to be a rocket scientist to come up with one. However the fact that this %5 rule hasn't been changed tells you everything you need to know about the legislators.
