But that 52% gives him the moral authority to "do his best" to take the country out of the EU. If he screws up a bit, who can blame him? It's a tough situation anyway etc etc.

You have to understand how those people operate. They don't give two bits about reason and making sense. All they care about is to stay in power. They optimise for that and that alone. And 52% is power, beyond BoJo's (or Gove's or Farage's) wildest dreams.

If Brexit was a big mistake, thinking that Boris will get cold feet now that he has a clear line of sight to his goal (to be PM, duh) is an even bigger one.
