I'd never heard of Blue Labour till now so had to look it up. If you think that's what Starmer is, you don't really get what Blue Labour is about.
"Writing in the Daily Mail recently, former Corbynite MP Dan Carden called himself the leader of the Blue Labour group in parliament (which, according to Wikipedia, has a grand total of three other members), advocating for a policy of re-industrialisation, immigration controls and universities being replaced by technical vocational colleges. In other words: turning the clock back to 1962, before globalisation and the expansion of universities spoiled everything."
Their "programme" sounds more your view than Starmer's.
Callaghan lost the support of his own base while losing the 1979 election to Thatcher. Any Labour government that tries to follow the Blue Labour formula is likely to end the same way.
