The Labour right view parliament as basically a finishing school for their PE degrees where they get to make contacts and plump out their CVs with handwavey initiative stuff so they can land some plum job in the private sector afterwards. Most of them have no real interest in power beyond the vice-like grip they have to maintain on the party to make it possible, so coasting into a comfortable L against the Tories is fine by them.
It’s why I have the tiniest amount of respect for the CUK-TIG people because as soon as the party wasn’t about that anymore they were out the door, they didn’t stay to continue fucking the membership over and over like Starmie and Watson did. And look at them all now: After the comical, abject failure of their political careers, where it was revealed they were all cretins without a single intelligent thought in their heads who nobody would vote for given the choice, they all breezed easily into PR and industry roles. They’re professional losers, every single one.
