A good chunk of "softer" Remainers would have settled for the WA, hoping sanity would prevail during extended transitions and we'd end up in a Norway++ type Brexit
I am one of the soft-Remainers who would have done... and I got annoyed at the Remainer-ultras - such as the LibDems - who seemingly wouldn’t accept the referendum vote. I voted for Tory in 2017 as I believed they were best placed to deliver Brexit in an orderly manner that minimised the damage and maximise any opportunities (though I always believed the damage would be greater than the opportunities).
However, when the WA failed for the 3rd time, I concluded that a deal was never going to happen with the current Parliament, and that we needed a referendum or GE to break the log-jam and avoid a no-deal.
With the time elapsed and the prospect of anyone delivering a deal being remote (if Labour win a GE they’d have no chance of delivering Brexit either) I’m back to wanting us to remain... though am now a more ardent Remainer than I was before and will probably vote LibDem should there be GE in the coming months.
I think many Remainer Tory MPs are on the same journey as me, just further behind me as they are far more emotionally and practically attached to the Tory Party than I ever was.
