Just my opinion really as a young Labour voter myself, for what it's worth.
Looking into it though:
According to the same poll, Starmer has better ratings than any opposition leader since Tony Blair. But it’s the underlying data that should prove more alarming: among the under-35s, just 26% are satisfied with Starmer, compared with 38% who are dissatisfied. Corbynism attracted more younger voters to Labour than at any point in electoral history: but they have less loyalty to any political party than any previous generation.
Young people want a strong state to bring about social equality and a green economy, but Keir Starmer isn’t offering this, says Guardian columnist Owen Jones
