The snp got 10% of the vote in 2010. Now they looking at 43%.

I wonder how many of those 43% have been told not to waste their votes by voting for the 3rd largest party in the constituency? Yet now they are the biggest party so tactical voting could now see tories backing labour and vice versa.

Strange old world tactical voting. I do get it, but I think it can lead to unintended consequences as you don't know how parties will behave after the election (all the labour supporters who voted lib dem in 2010 to keep the tories out being a case in point).

I really do think the best way is just vote for your favourite party/candidate. If everyone does that at least the result will be genuine.
