There is no optimism. It wasn't an optimistic campaign. Whoever won, cuts were coming. If all goes well (which it wont) it'll take the best part of a decade to get the country back on track and will take a lot of wise investment for the future.
I think people don't realize how precarious a position the country is in - and while that isn't entirely the Tories ' fault, Brexit is a big part of it.
But I do expect Labour to be voted out in 5 years when it turns out that Starmer can't wave a magic wand and fix everything.
