They got excoriated by a small, but very vocal, portion of the electorate (wealthy pensioners). If they had stuck to the policy then it may well have delivered some respect from other portions of the electorate. Instead they U-turned and raised taxes. Nobody thanked them for that - not the wealthy pensioners nor the taxpayers. Same again with two-child benefit. U-turn and raise taxes. I don't think there is any way back for Labour now regardless of who is leader.
An awful problem in this country in the last decade or so has been the unwillingness to take tough decisions. Sometimes there are some people who lose out as the result of a government decision and they will be vocal and you may even lose council elections or parliamentary by-elections or slip to third in the polls; it doesn’t matter, you should just crack on if you think it is the right policy, as you think it will bear fruit in the long run. Yet every leader since Cameron has just wilted at the first sign of pressure. Not coincidentally he was the last PM to be re-elected. Consequently no decisions are actually taken, which is worse than bad decisions being taken. There is just anarchy and drift. It is like every bad manager any of us have ever had.
The main way this manifests itself is that the government won’t say no to vocal interest groups’ demands for money, with winter fuel being the prime example. So the country is skint and has a general feel of decay.
I would have had a lot more respect for Starmer if he had stuck to his guns on this one, but no, it is apparently impossible to cut public spending. He should have said “the country can’t afford it, they don’t need the money, we are thinking about the future of the country”, but no, they chickened out. Most recipients probably didn’t vote for Labour anyway! See also the welfare reform rebellion.
It’s a cliche but compare Thatcher, still a hero to many decades after her death, to the PMs of the last ten years- derided and forgettable. But she is only a hero to some because she was a villain to others! Trying to be friends with everyone just makes you a villain to everyone.
I think the electorate can cope with someone who is dull (see: Major) and someone who makes mistakes (see: Johnson), but I think what really got under peoples' skin about Starmer was his (and his cabinet's) piousness in opposition and how it hasn't translated at all into how he's running the country. So many of the things he repeatedly pulled up the Tory leaders over, sometimes to minute detail, are things that he himself has done and he just doesn't seem to recognise it. Hypocrisy is what really riles people I feel.
This is a further factor. Throughout the Tory government Starmer and his crew were like the Kirk elder, demanding ministers resign over trivialities. While Partygate was a scandal aspects of it were overblown deliberately. I personally also object to the idea that ministerial behaviour must be subjected to quangocrats for review. In a democracy politicians should be above bureaucrats.
Then Labour get in and they are accepting gifts from dodgy businesses, they are appointing one of the shadiest men in the country,- pals with the most infamous villain in the world!!- to high office, they are getting caught out dodging tax…it shows a real arrogance and stinking attitude. Talk about being hoist by your own petard!
I would also add one other factor which I have observed in politics. Sometimes a leader emerges whose schtick is “I don’t play games, I am a rather dull person who just gets on with the job”. Examples are Brown, May, Sunak, Starmer. Leaving aside the fact that many (eg Jess Phillips today) say Starmer does not actually possess the administrative competence to “just get on with the job”, the public like a charismatic leader and charismatic leaders achieve more of their goals.
