You say it was an easy win, but HC was once one of the top 3 most popular politicians in America and at the same time I've never seen people so enthusiastically support a candidate like so many support Donald Trump. They put flags on trucks and formed convoys to harass democrat campaign busses.
I don't know about top 3 popular, in the SE Hillary is probably one of the top 3 most hated politicians and land area wins elections here unfortunately.
She was far from popular, in 2016. How old were you 2016? Because research may not be painting you a good picture.
And if you were an adult, perhaps you were isolated? I don't know the explanation. But you are quite wrong. She has never been popular with the majority.
