This is what happens when you spend your money in blue locations who were already going to vote for you. Hillary Clinton is going to be a historical case study for a horrible political candidate and a horribly run campaign. When you win the nomination because the party decided it is their "turn" and rigs the primary to your benefit it becomes easy to over-estimate your sense of self worth among the American electorate.
I don't know where Hillary Clinton spent her money. I do know she let Trump both outwork and out campaign her. From 1 Sep through 8 Nov 2016 Trump made 116 campaign visits, stops, rallies, appearances etc to Hillary's 71. Her 71 looks larger than it was as it includes fund raisers in deep blue California and New York.
In the three deciding states, Wisconsin, it was Trump 5 visits, stops, rallies to none, zero for Hillary. In Michigan it was 6 for Trump, 1 for Hillary. Pennsylvania was closer, 8 for Trump, 5 for Hillary. Even in electoral rich Florida, Trump out worked and out campaigned her there 13 to 8.
Yep, a very inept campaign strategy for Hillary. If you call receiving more electoral votes than Obama a campaign strategy. She spent a lot of time, energy and money trying to win Georgia, Arizona and Utah. She shouldn't have ignored her backyard, the so called blue wall states.
2016 was the first time since 1988 that Michigan and Pennsylvania went Republican and the first time since 1984 for Wisconsin. I think she took them for granted. Had she won those three states, she'd be president today.
