notfromconcentrate I agree that there should be no place for petulance and childishness in politics, but a quick glance at any PMQs will show that a good deal of parliamentary politics is made up of precisely that.
As for Clegg's 'no more broken promises', I'm not sure that anyone anticipated a hung parliament resulting in a Lib-Con coalition. It's embarrassing for him to be now in the position of breaking promises having got all hoity-toity about it before, but saying he should have looked into his crystal ball and anticipated this is a bit beside the point.
I think it's symptomatic of a wider problem the Lib-Dems are facing. In essence, they're having to grow up very fast: having been out of power for a very long time, they've got into the habit of writing an 'In an ideal world...' type manifesto, safe in the almost-certainty that they didn't stand a chance of getting in and having to try and implement it.
The problem is, of course, that they're now in power - but as a minority party in a coalition. So they're suddenly in a position where they have to start giving ground, with a fairly weak hand, against their coalition partners in order to get some of their projects through. From the perspective of people who voted for them, each issue they've abandoned looks like a squalid betrayal, both of their voters and also of their high moral position.
It seems to me that Lib Dem voters have to choose between being idealists, and having the moral high ground but very little power, or being pragmatists, and compromising sometimes for the sake of having more influence. I can understand that some Lib Dem voters feel betrayed, but I find it odd that the response to their party being a minority partner in power, and hence having to compromise, is not to campaign harder so they're the majority last time. Instead, Lib Dem voters seem to be saying 'Well I won't vote for them again' - which means they'll be back to having no power at all. This seems perverse to me; but then I'm a pragmatist, not an idealist.
