@NeonPurpleStar It's not about losing entirely, but not come into power in order to be able to fulfill their promises. The reasoning behind this is explained pretty well using historical anectdotes and explains a lot of the behavior of the democratic party (such as with Bernie Sanders in 2016/2020).
So, what part of the statements mentioned in the video are false? My simplification of a title obviously couldn't convey the entire idea.
