CM was asked to provide proof that there were more than a few people supporting Trump on his visit to London. Naturally the mainstream media just covered the angry mobs and the baby balloon.
Of course many pro-Trumpers prefer to drink, not wear milkshakes. Or as BBC comedian Jo Brand suggested to people of his ilk (i.e. Nigel Farage) that battery acid should be thrown instead. Great joke in a city where acid attacks are almost a twice a daily occurrence.
