The usual suspects are telling us they will organise the biggest demonstration ever if Donald Trump visits London. They may well succeed. It will conveniently avoid confronting the fact that Jeremy Corbyn has led his party into an alliance with the Donald Trump wing of the Conservative party to deny young people the rights and opportunities which those older have benefitted from. One third of Leave voters have a good opinion of Trump.
There can be no Big Tent in British politics because the country is split down the middle over Brexit. Demonstrating against Trump can be no more than feelgood politics for those who are not so much disenfranchised as deprived of a political party - but unwilling to confront that glaringly obvious fact.
