Tactical voting vs sticking with preferred party

[Catren]

If you were soon to vote in a constituency that your preferred party will NEVER get elected in, would you still vote for your preferred party representative? Or would you go for a more-likely-to-win candidate who you don't hate but if s/he gets elected it will unseat the incumbent knobhead?

I feel like I'd be betraying my preferred party but perhaps the latter is the lesser evil. Thoughts please?

I'd vote for the person most likely to unseat the nobhead!

I'm firmly with one party but would vote for another candidate if that was the only option for getting rid of the current knobhead.

I would be careful with tactical voting in some circumstances, including the EU elections. Certain Facebook groups are pushing people in one direction without declaring their own political interests. Always worth looking at the people behind the various "non partisan" groups.

Remain Voter website has done a good number crunch of how to maximise your vote. The d'Hont system of party lists is really complicated so your vote is wasted if you don't vote tactically.

I would probably vote tactically as the outcome would be more beneficial overall

I'm voting tactically, usually a Labour voter but this time going for Lib Dem as best remain choice in my area. Although quite honestly so fed up with Labour re: Brexit, anti-Semitism etc in some ways good to have a reason to vote for a particular party. The Greens in my area have also been linked to anti-Semitism and in any case they seem a very ineffectual party, lacking in diversity and not strong on much outside environmental issues. I am thinking about Change UK for future elections but depends on how they shape up, their manifesto and so on.

The Lib Dems don't have a good record on antisemitism either. Baroness Tonge (not to be confused with Carol Tongue candidate for Change UK) was left to spout grotesque things from the Lords for years with the LibDems whip. As was David Ward. That's why I'm backing Change UK and fortunately they are the tactical choice in my area. The LibDems positions on a range of issues including inaction on antisemitism are part of the reason there couldn't be an alliance. The other reason is that all of the remain parties, under Electoral commission rules, would have had to dissolve and reapply as one party. No time for that.
