On May 6th the voters on Lincolnshire cast their votes. Here is the combined results for the seven constituencies.
Yet under FPTP the Conservatives managed to obtain all seven seats.
One of the possible options for an STV election would be to have a Lincolnshire constituency with 6 MPs. Based on the numbers above both Labour and Liberal Democrats should have at least 1 MP each and the Tories 3, the final seat either LibDem or Tory.
There are some problems however converting FTPT directly to STV. To start with the tactical voters in Lincoln who voted for Labour and in Gainsborough who voted LibDem to stop the Tories probably would have voted for the party they actually wanted. As these people were never asked if they were voting tactical we have no idea how many would have changed.
The smaller parties like the Greens only fielded on candidate in South Holland and the Deepings. This one candidate if standing for Lincolnshire could have received more votes across the county, removing them from Labour/LibDems.
Also if it was true STV with you voting in preference to your preferred candidate (not party) those who voted for the UKIP, BNP, English Democrats and Lincolnshire Independents would have their 2nd/3rd/4th choices counted as their first choices were eliminated possibly giving the Tories more votes. But I’ve seen enough council ballot papers where people get 3 votes where they have voted BNP, LibDem, Green that these votes could go anywhere.
Only one thing I do know, it is deeply unfair that one party receiving less that 50% of the votes gets every single seat.
