On the fifth of May a referendum will be held in Britain over whether or not the country is going to adopt a new alternative voting system, known as AV. The system gives voters the option to select multiple candidates in order of preference (they can still vote for just one candidate).
It is proving to be a very significant referendum not only for the influence it will have on British democracy, but also for electoral reasons as both coalition and opposition are divided.
Conservatives are opposed whereas their coalition partners the Liberal Democrats are in favour. Labour, being nearly the entire opposition, is on itself divided.
Across the political spectrum politicians are campaigning for a yes or a no to the AV system. Somewhat surprising to see is that Nick Clegg, leader of the Liberal Democrats, whom, of the three major parties, are strongest in favor of AV, is hardly campaigning it all, the most probable reason being that he doesn’t want to upset his coalition partners, the Conservatives. Ed Miliband, representing a divided Labour party, is in favor of the AV system and has become to represent the YES campaign. He’s being supported in his campaign by LibDem Business Secretary Vince Cable and sees his fellow party member and former Home secretary John Reid join Prime Minister David Cameron on his NO campaign.
I find it interesting to see how this issue shows to go beyond party politics. As interesting I think it is to look at what (electoral) motives politicians might have. You can be assured the politicians have thought about which voting system is most likely to favour them most in the future and it just might influence their position on the issue. Needless to say that this would be the last thing they would admit.
The main argument for AV is to avoid counties being won by a party that has a minority of votes. For example if in a county the party with the most votes only has 30% (or less), with the current system the county goes to that particular party, with the new system the 2nd , 3rd etc. votes will be counted until one party has 50% of the votes (or has most votes after all votes got counted).
David Cameron has said about AV that it will favor small “extremist” parties like the BNP or UKIP on the right wing. It doesn’t take a mastermind though to figure out that this is highly unlikely, the parties mentioned are so far from the political centre that they’re highly unlikely to gain sympathy from people voting for parties in that political centre.
