Really confused about TUSC and other socialist parties that aren't the Greens

Forget for a moment about Green Party policy and look at their relative success in the last few years... other than arguably Reform they are the fastest growing party in terms of councillor numbers(although they still have about 8x as many councillors as Reform, they are in administrations across the country including one where they have a majority and they now have 4 MPs

They've done this with next to no positive media coverage and without lots of rich donors.

When will TUSC and various other political parties on left look at what tactics the Greens are using and think about adapting them?

Selling newspapers like the Socialist Worker at protests isn't getting you elected...
