Whatever your political allegiance today is your chance to use your democratic right to help elect the MEP that you chose.
My wife and I chose to vote for the GREEN PARTY. As this election is by proportional representation even votes for minor parties are not wasted. I very much hope the GREEN PARTY does well and wins more seats. They would act as a moderating influence in Europe. Their policies seem very sensible, unlike some others. Their catch phrase is "for the common good". These days they have moved on a lot and some forecasts expect them to out-do the Lib Dems.
In a democracy, of course, you are free to vote for whoever you choose. USE your vote.
