The plural of anecdote is not data, but I get the sense that many left-wing Labour voters who might support them avoid voting Green (especially in the last two elections) for fear of "wasting" their vote. It would be interesting to see if that ever changed under a different electoral system (like the buried AV, or PR), but I'm not sure that we're going to see such a change any time soon. A party that got a real majority on just under 40% of votes cast isn't likely to wipe away that victory with electoral reform. But considering how high UKIP's vote was, despite returning only one MP, there may be more pressure to explore that idea again.
