Re: Power unchecked
I take your point re: rerunning until you get the 'right' answer, and it's why I'm on the fence about a second referendum now. Technically it's a different question — mutated from "these are some hypothetical benefits, should we pursue?" to "this is the deal so far, shall we continue?" — but if you follow that path of logic then I guess you'd end up with at least three polls since even May's current deal is, at least in part, to establish a transition period during which the actual final agreement is obtained. So a different absurdity looms.
The chaos in parliament and the prospect of a no-deal exit, which is a thousand miles from what most leavers voted for (cf. Gove, Redwood, et al and their beliefs that a deal would be easy), is the real tragedy here. That's not delivering on the referendum. That's admitting that the thing was so poorly framed and ill-prepared for that the whole system of government has failed to find a way to deal with the result.
On the issue of substance, the 48% I'm in lost. Game over. Farewell, EU.
