A vote for Labour in a Tory safe seat, especially one in which the Lib Dems are the second party, is even more wasted than the average. What's the point? Even if you think they are the best of the parties likely to get into government, a vote for them will in no way make this more likely.
Well I would like to see the system changed so that I can vote the way my heart tells me and still feel like it matters.
But judging by the runaway popularity of the Lib Dems at the moment, I will vote strategically and see if we can kick the career Tory out.
