No you're not being stupid but the landscape has changed a lot since the last election. Johnson has been discredited, Brexit has failed, the pandemic showed the value of public services and key workers, the hypocrisy between Britain and the West's reaction to the Ukrainian, Palestinian people who are suffering. Polls show even tory voters want change, they want a fairer tax system, more social justice and a country where the rivers and lakes are not full of shit due to Thatcher privatisation and they want good public services. They want a levelling up between the North/South, old/young, rich and poor. They nearly all agree the Tory mantra of Austerity has failed, its failed them, its failed their families and its failed their communities. Its obvious the Tory way has failed, its failed badly.
People are not asking for miracles, they just want a centre left government that's on the people's side. If Labour panders to the likes of the people they have been pandering to (these failed Tory clowns) to imo it could unravel pretty soon. Then things could become dangerous. It's where right wing populism breeds and takes hold.
