Tactical Voting

There has been a lot printed in recent days about Tactical Voting, from people saying 'It'll let the Tories in by the back door', to others saying 'Blair needs a bloody nose'. Actually existing has an analysis of the situation as it stands now, as does Nick Barlow, see also this post.

The situation is simply that a swing from, say, Labour to Lib Dem is not enough for get a Tory Government, a swing of 11.5% from Lab to Lib would result in a hung parliament, and a swing of 24% gets a Lib Dem government. At no point do the conservatives benefit, unless there is simultaneously a swing toward the Conservatives.
