"Inexperienced" when gauged in proportional terms to her fellow candidates.
No code words here just cold hard facts.
Certainly she is more experienced politically than anyone who is not in the "game" but it is important to note that she is the junior player on the field.
This may be a strength or a weakness but I suspect that a party membership that has an aging demographic may see her as not ready yet for a leadership role.
Also her memberhship drive results were rather uninspiring.
This rationalization makes your claims even sillier.
