If Boris Johnson was failing in the leadership contest, he might be tempted to give up and vote for May's deal.
Which we don't want. Remember?
First we need Theresa May out of that job. And Boris Johnson can make that happen because he can make sure that May's deal never gets through parliament.
Corbyn is against May's deal. But there are a few Labour MPs desperate to vote it through. Which, like we said, is what we don't want.
And Boris Johnson can do that, you see.
See, Corbyn can three line whip against May's deal, but he can't stop every Labour MP voting for it.
So what we need is for that to not happen. And who is stopping it happening? Boris Johnson.
And when she can't get it through, and when she can't she's going to resign, which is what we've been waiting for for the last three fucking years
And how is Boris Johnson going to win that? By offering another referendum.
ARE YOU SURE?
Yes.
After that he's got a very simple choice. He can try and pursue a no deal Brexit, and his government will collapse before it's even started.
Or
Or he can have a general election and put another referendum in his manifesto.
