During a discussion over the pros and cons of AV and FPTP (and PR) someone made the comment that AV was pointless as "it won't affect most MPs, only about a 100 or so". I replied that I didn't think that sounded right.
But it doesn't matter if it doesn't sound right to me, it only matters what the data shows and as it so happens I have the 2010 election results. The statement posed was that the majority of MPs won't be affected by AV as they've already polled over 50% of the vote; the results below show which didn't:
|Scottish National Party||6||0||0|
|Social Democratic and Labour Party||3||0||0|
That's 433 out of a total 650 MPs whose winning position might be affected by AV.
