Yes but you clearly don't understand, they are a populist party - that means they tell you exactly what you want to hear and they say it loudly. Just like good old Nige during Brexit with his bus telling everyone how many millions would be able to go to the NHS after Brexit. Just like Trump in the US telling everyone he's going to make America great again.
If you want your country to work you don't vote for people with no experience who don't know what they're doing just because they're saying all the things you want to hear.
There is the same attitude as Brexit because Brexit was/is a complete disaster and we're now scrabbling for closer ties. People believe the lies though because it's what they want to hear.
The reason council tax goes up so much every year is to pay for social care, we have an aging population, there are an increasing number of kids with SEN that need support. People want the roads fixed, they want frequent bin collections, they want buses for their kids to get to school, they want visible police but they don't want to pay for it and choices have to be made by any council. It doesn't matter who gets in, the budget is still the budget.
Just because someone promises you the world doesn't mean they're going to deliver any of it, but people fall for it every time.
