Zack Polanski in front of a green map of London

According to new polling from Ipsos, more than half of Londoners are considering a switch to the Green Party. This is good news for it, but it’s also a sign that they need to keep fighting to earn every vote.

And this isn’t the only positive poll for the Greens either.

The Green Party on the up

As Kenyon notes, the Gorton & Denton by-election proved to voters that the Green Party aren’t a wasted vote. That by-election showed us something else too; namely that polling tends to underestimate the Green Party.

The following was the final tally in Gorton & Denton:

‼ Gorton and Denton by-election result:

🟢 Grn: 40.7% (+27.5)
➡ Ref: 28.7% (+14.6)
🔴 Lab: 25.4% (-25.4)
🔵 Con: 1.9% (-6.0)
🟠 Lib: 1.8% (-2.0)

In the runup to election day, some polls had the Greens in the lead, but they didn’t have them outperforming the runner up by 12 percentage points:

While the latest poll is good news, leader Zack Polanski is urging his fellow Green Party members to keep up the energy:

This is all really promising – but there’s no space for complacency at all. Nothing is certain.

We will be out campaigning for every single vote in the next couple of weeks.

The Greens have had other favourable polls too:

There’s a scenario here where the Greens gain more seats than reform on May 7th?? 🤯

That would be absolutely wild. More in common polls don’t even usually put the Greens as high as other pollsters. https://t.co/iyf8mb8tMP

In full, the post Gardner is replying to reads:

More in Common Locals Seat Projection Scenarios:

Low Estimate:
Reform: +1,273
Green: +573
Lib Dem: +148
Labour: -1,867

Reform: +1,437
Green: +926
Lib Dem: +327
Labour: -1,738
Conservative: -627

May 7 Briefing

In other words, the Greens could do well in May, or they could do really well, or they could do really, reallyfucking well.

The poll story

Of course, polls don’t actually predict the future, and not every poll is brilliant for the Green Party. As we reported earlier today, the latest YouGov poll presents a favourable picture for Reform, but they also had positive predictions in Gorton & Denton.

The Greens are clearly persuading voters that they’re worth considering, and that’s a victory regardless of how many seats they ultimately win.

We deserve better.

And we can vote for it on May 7th. https://t.co/SLQItLk61O
