The thing I'd say is that they're aware of their weaknesses and that they won't be solved overnight, but they know what the direction of travel is.
Lacking policies beyond immigration is one. That's what Danny Kruger and James Orr are dealing with, and they'll be bringing academics and think tankers on board.
The party being a Farage personality cult is another. He's indispensable, but they are making sure other people get lots of media and it looks like they have a team.
And tied to that, the lack of experienced people. Defections are the main way of dealing with that, but they're being careful about defections. They don't want to be a lifeboat for washed up Tories. I've heard from good sources that they've turned down 18 sitting MPs. To be accepted, you have to show you've got something to add to the party. For instance, Jake Berry was party chairman, he's been in the cabinet, he's an excellent campaigner who's steeped in red wall constituencies, so Jake being a remainer in 2016 is neither here nor there.
And as a bonus, Ben Habib's Advance party is a magnet for the racists and conspiracy theorists on the fringe of Reform. The general attitude from Reform activists is that if Ben wants their lunatic fringe, he's welcome to them.
They aren't yet where they want to be in terms of credibility of course. But they have a plan. That contrasts with the Greens, who are mostly relying on renewable energy generated from Zack's bullshit.
