What goes around comes around.
Might end up with minority govt and minor parties having more influence.The Greens or LibDems are the usual alternative destination.
The lettuce inevitably leads to the former as best choice - worthy, decent, environmentally sound, politically neutral, well intentioned with almost no chance of forming the next government. You can confidently assert you did not vote for the government, no matter who wins or how bad.
LibDems have a small core of support and attract dissatisfied Tory and Labour voters who can't bring thenselves to vote for the other side.
