Spoiling your Ballot Paper is the sort of thing that lets the extremists in ! Vote for the party that is ,in YOUR opinion, ,going to do least harm !
And Agitate for a NONE OF THE ABOVE option on ballot Papers !!
The thing ALL the politicians count on is a LOW turnout , then the active political types can run things !! Take your vote for a nice walk on may 5th - EXCERCISE YOUR FRANCHISE !
