I still can't believe the UK got suckered into the Fixed-Term Parliaments Act. All it took was like two years of making you vote every three months and you gave up your democracy.
You're not like the US. The US turns over a good portion of Congress every two years, and re-elects what is basically a active King every four. All you did was make sure that no one in government has to think about the public for a second, while they do what their backers and buddies ask, then retire in five years.
There's no way out of it. Starmer should try to get down to an <10% approval rating just to make the history books.
