Protest (blank/white) votes are a way of expressing your opinion, however I don't think politicians take these seriously! At least not where I live!
In my country such ballots are counted as invalid! People talk about that for day or two and then simply forget about it!
This is mostly true, but, if enough people spoil their vote in the same way it can be very powerful. In one constituency in Ireland a puppet turkey from childrens's TV out-polled one of the candidates. Sure, the votes were all counted as invalid, but it made quite a splash, and sent a strong message that people demand better.
Voting system here is designed to favour only two big parties (left and right) and their satellites, so small parties and citizen initiatives can hardly pass!
For example if you vote for small party (e.g. Green) and it doesn't reach necessary 5% threshold then your vote is automatically distributed between big parties!
We are a divided bipartisan society! But I guess it's pretty much the same everywhere!
It's not the same everywhere actually - there are electoral systems specifically designed to give small parties a fair chance in some countries. Ireland is one example - our system is complicated, but, the seats in parliament tend to mirror opinions quite closely, with small parties actually getting some seats.
The key to the Irish system is that your vote is transferable - you don't give it to one person, but you rank all the candidates you like in order. Your vote first goes to your first choice, all the first choice votes are counted, and then the person with the least votes is eliminated, all the votes for that person are then passed on based on the second preferences of his/her ballots. This continues until there are the same number of candidates left as there are seats - so in a 3 seat constituency until you get three candidates left. All the constituencies are between 3 and 5 seats depending on population.
In the US or the UK if you vote for a small party you are in effect wasting your vote, because you get no say over which of the two big parties win, and one of them inevitably win. With the Irish system you can safely vote for the small parties, and, if they don't get a seat, your vote is not wasted, your second, third, fourth, etc. preferences continue to count, and your opinion continues to matter.
