There's no question about it.
Teresa May is going to be talking Brexit. Nicola Sturgeon is going to be talking Brexit. Tim Farron is going to be talking Brexit. Talking about Brexit helps each of them in their own way.
You know who doesn't want to talk about Brexit? Jeremy Corbyn. Because Brexit divides the Labour Party. Talking Brexit hurts Corbyn.
Corbyn will want to talk about a lot of different things. Things that unite Labour and may even be popular. But it won't work. Brexit is the most momentous event in Britain in decades and it will be front and center no matter what Corbyn says about other topics.
May's message on Brexit will be simple: the people have spoken, lets unite and get on with it. That will be sufficient for much of suburban and rural England. Wales too. The Conservatives are united for Brexit.
Sturgeon's message will be simple: the Tories want to impose Brexit on Scotland against its wishes and she will fight them. That will be enough for Scotland. The SNP is united against Brexit.
Even Farron's message will be simple: We hate Brexit because its fucking stupid and we will stop this madness. That should be sufficient for the wealthier London boroughs and other large cities. The Liberal Democrats are united against Brexit.
Corbyn, however, will need nuance. Corbyn's party is split on Brexit, with large chunks both for Brexit and against it. He's in quite a bind. Corbyn needs a clear, compelling message on Brexit. I don't think it can be avoided for discussions about neoliberalism or austerity. I don't know if he necessarily has to choose a side, but he definitely needs to clear enough on this issue to unite Labour behind him. If Labour remains divided, its over.
Its going to be a fun election to watch.
