I am amongst the priviliged minority of voters who can vote for the party we want to win, knowing that our candidate has a good chance of winning.
I support the Liberal Democrats and live in a constituency where the only two parties which could ever win are the Liberal Democrats and the Conservatives.
It has not always been like that. When we first moved here the Conservatives controlled every level of government - Parish Council, District Council, County Council, MP and MEP.
Gradually, over many years that changed, thanks to the hard work of so many Liberals and then Liberal Democrats, we started to elect councillors who did a good job, then in 1985 took control of the County Council. By 1997 we had our MP and a brilliant MEP.
I feel lucky to have been able to support good candidates who actually got elected and I understand how difficult it must be for people who passionately support the Labour Party and the Green Party in an area like ours, and for fellow Liberals in areas where our party never even comes second.
That is just one of the many disadvantages of the First Past The Post Electoral System which we must campaign to change to Proportional Representation if the UK is ever to become a true democracy.
