She also just wasn't likeable to a lot of voters; she came across as phony in a lot of her appearances. Not to mention all the shadiness around whether or not Biden was declining (and how far) and her role in (potentially) covering that up. Biden also ham-stringed her by waiting a month to drop out after his disastrous debate performance and then immediately endorsing her (skipping a primary process). There's more but I think these are the highlights.
