It's natural there will be an element of 'crowing', or whatever you want to call it.
There was a certain element among some LibDem voters* in the lead up to the election of self-righteousness, in the vein of 'look at me, I'm dead radical I am'. When asked about the neo-liberal economics, the various tory-like aspects of their policies, their history, etc., the response was usually in line with the fluffy-wuffy spin that attracts people who want to be progressive but don't want to do it outside of the big 3 - socially progressive policies trumping neo-liberal economic realities within the party.
When some of these people work out things aren't what they first thought (despite having had it suggested to them beforehand) it's pretty natural the people for whom it was bleedingly obvious, and for those people who tried to argue it, to crow. People are petty, and they like to say I told you so. It doesn't mean they're happy with the current political situation, but they're quite pleased with themselves that at least they didn't pretend things were anything other than they are beforehand.
