In part Obama, and part herself. She should not have campaigned on the status quo or pandered to the "Obama Coalition".
obama's approval ratings are (and were) actually very solid, so…?
Only in the final months of his presidency. A year or so ago they were in the low 40's (even in the 30's!).
Also, 70% of the population believes the nation is on the wrong course, and over 60% believe Obama's policies should not be continued (according to exit polling).
Anyone who embraced the status quo in 2016, was doomed to failure (attaching themselves to a sinking ship). The only way a status-quo Democrat could win was through fear. Once a government is reduced to fearmongering to avoid defeat, their time is up.
