There were 3m more Labour voters in 2017 than there were in 2024. There's lot's of people that could turn to an alternative left-wing party. There were 3m Lib Dems and 2m Greens at the last election and 4m Reform. Don't forget that votes tend to be concentrated so Labour wins in cities that see a deflection to Corbyn could be enough to take seats from them, the same way Reform did from Tories.
It's extremely unlikely that a Corbyn party could win the next GE but it's not unlikely that they could do what Reform have done and flip Labour. A one-off Reform government that leads to the alternative party being left-wing could be way better for the long term than the left wing choice being centre-right Labour indefinitely.
I don't think Corbyn would intend to lead the party either.
3m more voters is irrelevant when you stir up even more on the opposite side and lose, it's a net loss, and an election loss.
Reform have taken a load of Tory votes and seats (largely those far right) and wouldn't have had much chance at the next GE, but this probably now makes it the most likely outcome, great. They're going to make Truss look competent.
Reform have also seemingly taken some Labour votes from those on the right of Labour, I'm unsure why this is but it ain't because Labour are on the right is it?
It's seemingly happening though, Labour will bleed to reform, and Corbyn isn't going to take those back, he would take votes from the Labour left. So Labour end up attacked on both sides, which is all a bit silly after one year, when they've mad more positive changes in that time than 14 years of the previous folk (on all sides).
All this is going to do is split the left to centre vote, at a time when it's under massive threat, I wish people would just be honest and say that.
He's not winning the GE, he couldn't win the two horse race when the Tories were weak, so he's not winning a 4 horse race. He needs more votes and seats than reform. He's talking about Gaza when they're talking about immigration. It's policy rank 20 v rank 1, in the eyes of our voters overall. Our voters are dicks, but they still will be voting, can't ignore that.
Of course he's going to want to be leader, and of course everyone joining in on this, voters and MP's is going to want him to be leader, it's nailed on.
It likely won't be a one of reform government, if they do win, they would be doing it under confidence and supply (as a coalition with the Tories, who they will then blame), and when that doesn't work they will likely kill off the Tories and win outright. We could end up with those clowns for 15 years. If Labour had that time they could really turn things around, but things won't be turned around fully in 1,5,10 years, people need to understand this. The Tories dug a very deep hole, in many ways.
We've got a lot of people on the centre, centre right, right, far right and they're not going to disappear. It's going to take a long time before they die off and are replaced enough with left leaning voters, we might be ~10-20 years from that.
The only way to winning or holding power at the minute is holding enough of the centre.
