I'd fully support a vote if rejoining was one of the options. It's pretty clear from polls that support to rejoin is far stronger than the support for Brexit was (in June, it was 55% for vs. 34% against, vs. 59% in support of a closer relationship and 20% against, and 29% supporting the current relationship).

But in the meantime it is also entirely unambiguous that there is a clear mandate for a closer relationship - the gap is so huge (much larger than the support for the current status quo ever was) that there's no real need for another vote for that and voters can punish parties that support it at the next general election.
