Its not just Maomentum as i like to call them, there are many issues with the current Labour Party it may take 15 years for them to be ready for power.
There was multitude of reasoning to why Labour lost, here are some of the reasons formalising my analysis.
I heard people talking about a hung Parliament prior to the election results but i didnt see that- anyone who understands the numbers would have predicted a Boris majority. All be it my prediction on other places was 335 seats not 365 so they even exceeded my expectation
1.) Brexit
The prominent issue which lost them core support. The issue they had Leave Labour supporters in the Midlands and North HATED the brexit policy after voting to leave the EU in 2016 with a majority of 1.2 million votes Labour was telling us that wasn't decisive enough and we should negotiate a customs union and Single Market (pretty much same as EU membership only without representation) Then put it to a second referendum against remain. Effectively giving an option of a remain vs remain second referendum. The north and urban midlands areas (Dudley's, Sandwell, Walsall) seats switched blue. One of the Birmingham seats switched blue the rest Labour Retained, demographics and democratic plantation of voters pretty much ensures Labour big towns and cities.
Jeremy Corbyn
What a joker this man was 3 years of a party being led by a bystander anything popular amongst electorates he disliked.
National security? No he liked negotiating with terrorists and did it many years as a back bencher with IRA and Hamas.
Strong economic plan? No his plans was utopian and would have cost trillions i truky think the 1.4 trillion costed Labour manifesfo was a little low for what they wanted to spend and that is correct as they promised more and more free stuff which was away from manifesto
Likeable character? No not at all he just shouts his mouth off to then get put back in his box by the primeminister now by Johnson but also previously by Theresa May our worst primemimister since Lord North
Policy
This is the area where they was batshit mental! There own NEC didn't help them at all.
I'm not 100% sure if it made this years manifesto but at the party conference the cult of Corbyn's far left leadership decided extending freedom of movement to the entire world would be a good idea and considering if they won power we'd have ended up remaining if Brexiteers thought an open door to 510,000,000 was a bit much there response would be How's about 6.5 billion more?
Next up is my favourite Labour Policy of their 2019 manifesto this is a very stupid one. They wanted to renationalise the railways which would cost in excess of 200bn- don't forget this is a business which runs at a low profit margin of 1-3% then not only using public money to purchase the utility they wated to cut its revenue by over 33% by cutting ticket prices by a third and giving 16 yearolds free travel.
Then you have the free internet policy, the list goes on people understandbly saw there policies shook their heads, held there nose and voted Tory- if they couldnt vote tory they'd have voted Brexit Party syphening support away from Labour making it easier for tories to win seats.
Trident
Emily Thornberry said they are against ever using trident- most say they'd use it in extreme circunstances but if Labour was elected they'd have had an emergency meeting in circumstance it may need to be used and make a decision! While that joke of a cabinet would be deciding we'd all be dead.
How do Labour come back as a party which is electable
Firstly ditch their euphoric support for European Union
Get a right leaning leader in, I think Sarah Champion would be a good choice on their right.
Do not pander to trade unions.
Purge the marxists such as Corbyn, McDonnell, Rebecca Wrong Daily (real name Long-Bailey), Angela Rayner and there ilk.
Embrace capitalism but with more personal freedom the the tories.
Run at a balanced budget.
Cap immigration.
Some will say this is Redkip but that's not a bad shout if they want northern and midland seats back.
