Starmer likes to go out and meet people. He has been doing it a lot ever since he became an prospective MP, but he doesn't like cameras following him, so it's not widely known.
Starmer is thorough, organised, extremely hard working, a details person and, when it comes down to it, ruthless. He has two weeks final preparation time before the campaign proper. He has nothing to do to finish off and discredit the Tories. The people no longer need any help coming to a view on them, that is formed. I think his campaign will actually be primarily focused on positives about Labour and it's visions and plans for the future, though tempered with realism about the size of the tasks ahead and what is achievable. His solutions will be pragmatic, not ideological and so they should be.
The debates can make a small difference, but Starmer has some time to prepare and he will do that. He is not comfortable 'performing' but he is not up against a Johnson, or a Blair, but a goddam Sunak. If I was Sunak I would be the worried one. Sunak has been so concerned for years about assassins knives in the back and only amateurs around him to help, he should focus on the guy in front of him as he stands alone in front of the public, with no-one to protect him. Then he might just see the deadly killer who put his predecessor out of the Party when he was getting in the way, has took down governments, multinationals and organised crime groups in the courtroom and didn't hesitate at the September 2018 Labour Party conference to act boldly to stop Corbyns brexiter inner circle betraying the wishes of the members and reverse an agreed position of the Party on Brexit. I can't see him hesitating if Sunak presents any opening, which let's face it, he is so useless he will.
