Voting against someone rather than for someone is a sure-fire way to get some of the worst politicians in power as possible, they only need to be marginally less bad than the other candidate after all.
Restore Britain is a populist joke btw. Greens might be my side of the fence but they’re also populist. Hard to get air time as a small party without some form of sweeping emotional appeals and “common sense” thinking, even if it’s internally inconsistent and very broad.
