If you believe the polls, the supports been dipping: think there was one last year at 56% to leave, now in and around the bottom 50's; so i think the infightings had an effect. They've always wanted to portray themselves as above liars in the Tory Party (their thoughts) and it's probably taken a shine off it for some. That being said, short memories and all that, i wouldn't be surprised to see it rise again back to that level.
Whether she gets her dream or not, not sure, but it's going to be a close call: lots of moving parts at the moment and, after the pandemic and Brexit, the timings going to be key. I'd hazard a few quid though it'd be a very narrow Yes vote if held in the next 6months still (not that it'll happen)
Opposition parties here made an arse of it themselves - calling for her to leave without the report being published - the actual committee at the end of last week was a joke - all sides voting along party lines; each entered that enquiry already knowing what they were voting for.
