Mostly because they didn't live up to their values in the past at all. Underperforming despite plenty of opportunity and lacking integrity is just too much. Blaming it on an opposition is weak and translates into lack of power, lack of strategy, and lack of volition.

They are being auto-promoted by actors like von der Leyen, who blind specific population segments like moms and women who are trying to make it while negatively impacting any orbit they are assigned to and shoving tons of money to consultancies and the likes.
