Worst case scenario is that they rule a small breach that she would be able to brush under on the basis that it would be petty to expect resignation over and folks would also add in support that poor wee Nicola was getting a hard time over something inconsequential so gains her more support.
She doesn't intend to resign regardless but obvs things are changing daily.
I think the intention was to drip feed so that people get fed up and each thing seems like a small thing as they don't consider the totality of the evidence. That may backfire though as it's keeping it going for longer and the election creeps ever closer.
For the anti indy folks I think the worse thing would be for her to go now and get a new broom with lots of promises in in good time for the election - where a new broom could be found is a mystery though.
On balance I think for me, i'm happy to see it kept in the news and each time another chip on the veracity of the NS submission and the failure of those around her also to add. There is still a huge core that will forgive anything in order to get indy, none of this will change that core vote, It's the undecided and the unconvinced that will be key.
