I agree. Someone more likable and without the Clinton baggage would have won. Her personality kept her from cashing in on the Bill Clinton goodwill, which might have outweighed the baggage, especially among the AA population. Events had broken in a direction which made many even question the state of her marriage to him, anyway. Without the Russian boost, she probably would have scraped out a win. Hell, even Bernie might have scraped out a victory over Trump...Honestly, her problem is that she is just not likable. She is the wife of a politician, not a politician. She has no political acumen, and she has no charisma. She might be "clean" but that is not what gets people elected.
She has the personality of a sponge.
