No, what happened was they became the lesser partner in a coalition, and delivered a lot from that position (the policies during that period were much, much better than they would have otherwise been). The idea that somehow they should have delivered on all of their policies from that position is laughable. Would they have been better served not being able to influence government at all? (This all goes to show how broken FPTP is, of course.) Then, because of thinking like that in your post, people gave up on voting for them, despite being the best possible representation.
