Whilst (so called) Labour voters look inwards and argue amongst themselves about this and that the Tories unite and harvest their natural and broad vote of country dwellers, southerners, business owners and cap doffers.
Divide and conquer, an old Tory tactic which is alive and kicking to this day.
Starmer would do well to spend time on countering this sort of problem particularly on social media sites.
I'm not so sure, the Tories aren't uniting, they have about 10 MP's going for leadership, and their voters are jumping ship in droves, it's the fastest and largest turnaround I've ever seen I think. It's not so much uniting, it's that the boat is getting smaller, so all that's left are the hardcore who will never move, and they're being bunched in.
It seems to be mainly some of the Corbyn fans who are miffed, and the Starmer fans (or just general Labour/ Tory opposition fans, like myself) are just a bit disappointed they won't jump on board and add pressure onto the Tories. I think this is getting better though, and will get better over time, it's way better than it was 2 years ago.
It won't make much of a difference though (to the GE outcome), as no Corbyn fan is ever going to vote tory, and every voter Labour hoover up from the Tories acts like two voters, if they switch sides. So if you lose a Corbyn fan you're -1, but if labour gain one from the Tories that's +1 to Labour, and the Tories -1. So overall Labour end up 0, and the Tories -1, which is a net win. In reality it works better though, as for every Tory that switches sides, you're not going to lose one of the Corbyn fans, hence why Labour are polling so well.
The same happens if a Tory doesn't vote, and one from the centre does (and votes Labour).
You've also got the coalition options too with those who jump ship to the greens or Lib dem or whatever, albeit I don't expect many Corbyn fans going to LD. Tories have a poor chance of getting more seats than Labour (although I expect them to improve with a new leader), but they have even less chance of a coalition with Green or LD.
It's hard to represent the entire political spectrum, who are against the Tories, but if Labour had to lose votes from somewhere, then tactically it would be better to lose the ones who won't ever vote Tory. I think Starmer is doing the right thing, by not countering the problem, as I don't see it as much of a problem.
We've got the worst Tory government I've ever seen, so priority 1 should surely be getting them out, and I'd vote for whoever had the best chance of getting them out.
