Boris and the anti-European media thought it would, when they made up and circulated that lie about Turkey being about to join the EU, and millions of Turks being about to migrate to EU.
Farage and the anti-EU campaigners thought it would, when they published a poster of Syrian refugees (blotting out the one white face in the original photo) and pretending that they were EU citizens who would have to right to move to UK.
They must have thought that anti-foreigner sentiment among racist Brits would bolster the anti-EU vote.
They were right.
