Welcome yourself into the new modern crisis
Because anything else is essentially a waste of your time under the current system. You can vote for the monster raving loonies, but it won't make a difference to anything. You have the power to choose the next government but with the current system that's only a choice between 2 candidates in almost all areas.
In my area it's a choice between Lib Dem or Tory. If you vote anything but Lib Dem you are essentially backing the Tory candidate. I don't like the system, but it's what we have. Very few areas have more than a 2 way split.
My perfect result at the moment would be a Labour Lib Dem coalition. Cross-party politics makes much better policies as it tempers the extreme ends of Politics.
So to obtain your desired outcome of a LibDem-Lab coalition I would vote Lib Dem. Or to express dissatisfaction with the current system and to encourage smaller parties and promote change I might vote Green as they've been gaining momentum. By giving them support it might show people that it could be worthwhile voting for smaller parties so they'll get out of the current mindset of feeling they have to vote Lib/Lab/Con as the only choices. That might shift things in their favour so they could get more MPs in subsequent elections and ultimately lead to electoral reform. I think I've always been clear that my number one electoral priority is to get the Tories out, but I have good reasons for voting the way I do and it is not always because I think the candidate I vote for will win on that particular occasion, nor that I think or want that their party should form the next government.
But this, according to Labour, is enabling the Tories.
