Now that we have much more information, it’s not unreasonable to reconsider.
More realisticly this is would be the next election on the same idea. Treat the options like a political party.
The leave party made a lot of promises and people voted for them. They came into power. The leave party has no been shown to be pursuing, criminals, and incompetents over the period of their rule. Why not have the next election now so that the parties rule can be assessed?
Every election is a really a referendum on the promises and actions of the previous one. The US did it with prohibition, the UK could do it here.
Or maybe it shouldn't, in general, vote at all on that as a separate question (after first resolving if people really want to go forward with the current exit process now that there is more clarity on what that entails) except perhaps to confirm it reject an exit under a deal negotiated after a government-decided invocation of Art. 50 provides a concrete choice, since it's a complex question involving potential for negotiated terms that intersects with every other policy area; maybe the UK should vote for a Parliament and let Parliament balance the issues, proposing referenda only when the public have he information about the choices that makes the decision meaningful.
The first referendum on Brexit was a fairly naked political ploy to punt on exactly that Parliamentary duty with the hope of creating partisan advantage in a general election.
…Yes you can.
A general election is always the same question, and sometimes we come up with different results.
