I think that’s why Nigel Farage quit politics immediately. No way that /edit/ guy /end edit/ is going to risk taking any responsibility for the consequences.
The sad take away from this, for me, is that even though politicians may seem stupid, they are mostly acting stupid because that's what gets you elected. They are not stupid, just ruthless.
That's certainly the perjorative view. On the other hand extreme pressure and death threats might cause one to wonder if the game is worth continuing. How many of us would enjoy that? Given that the whole point of UKIP (as far as I can see) was to ignite the Brexit debate leading to the referendum, the job was done and UKIP had zero chance of doing anything else. Farage failed to win a parliamentary seat so why would be subject himself to further non-profitable activities? He was a successful trader prior to his entry into politics.
Pretty hypocritical to keep spouting anti-immigrant ant--EU rhetoric when you have different plans for your own kids.
