Bring back hanging
There is more choice for people who find that formerly safe seat has become more marginal. That all safe seats don't fall into this category doesn't mean their aren't real gains for who do.
And *all* voters have the opportunity to vote for their genuine first preference, rather than the tactically necessary option eg. in LD/Con seats Labour/Green supporters can vote meaningfully for their own party without surrending their ability to influence the outcome in keeping the Tory out. That is a "choice" that doesn't exist at present.
Now they have a three way choice! Pluralism in action.
