Yes, the Brexit Party will "win", if by win we mean "take the largest share of the vote by a single party". But that's largely irrelevant. This isn't first past the post, winner takes all. They get nothing except MEPs.
In the 2014 European elections, the Tories and UKIP took 43 out of 73 MEPs.
At the moment, the Tories, Brexit Party and UKIP together look like they're only going to win between 34-38 MEPs.
So it's essential not to lose heart in the last few days counting down to the vote on 23 May.
It is impossible for the Brexit Party to win the elections, because there's no prize for coming first.
And part of that is getting the message out, as strongly as you can, however you can, that Labour are not a Remain party.
