Will be interesting to see what happens with the big two leadership wise if the current projections turn out to be correct. Davidson's tenure has largely been one of general improvement for the party, but this would be a complete embarrassment and she'll be worried if Boris takes over considering she's on the opposite wing of the party. Granted, it won't stop her from placating him at every turn for the most part, but still, could make for some inner party politics.
Leonard is basically
there and there's not much that can be said for him at all, but a terrible result might force the hands of those in the party who don't like him and who want change. However badly they've already done in Scotland 6% is utterly chronic and fairly indicative of the leadership - both in Scotland and beyond - I'd say.
Rise of the Greens has been interesting considering they only ever tend to be a factor in Holyrood - they've even managed to get an endorsement from the Sunday Mail which is quite remarkable considering (again) they've pretty much been a non-factor till now in UK-wide votes.
As a side-note UKIP-wise:
yer man from the Nazi pug video is standing for him, and is 4th on the list. Considering how his party are polling, unlikely he'll be off to Brussels.
Not to mention Change UK's main candidate is now voting Lib Dem! Fun times.
