There is a difference between believing whether their was a party, and caring about it. There is an even bigger difference between caring about the lies and it making you think there are better options available.
That's the key issue Labour and the other parties face. We know politicians lie. They've always lied and always will. Maybe they don't start out intending to lie, but in the end they will realise they need to say what they think their audience wants to here. You don't have to like a Prime Minister or even trust them to think that they are the best of a bad bunch.
To me, all the things Tory MPs are accused of doing - lying, breaking lockdown, having second jobs - don't really make any difference to the fact that however badly they run the country, they're more clued up than Starmer and his crew.
Labour don't exactly have a glittering record when it comes to MPs behaving themselves. Whether they're MPs are convicted of harassment, repeatedly been in trouble for assault or just a good ol' fashioned anti-semite, they don't suggest that the calibre of Labour MP is any better than Conservative.
The lockdown party is a distraction and irrelevance. It doesn't determine how well the government manages the Covid crisis.
