"A new report shows the Harris-Walz campaign and its Democratic allies spent nearly $1.4 billion on aired political ads in their failed bid to defeat
President-elect Trump, outspending the 45th president and Republicans by nearly $460 million."
She spent more than $460million than Trump, so even with Elon Musk spending it did not even come close to what her spending was. She ran a bad campaign that did not ignite the Democratic electorate to come out and vote for her. One main problem was her inability to articulate solutions to problems many Democrats had, because her Corporate handlers would not allow her.
This problem will remain with every candidate in the Democratic party, if they are beholden to corporate money. It also shows though, that the most money does not always translate into the most votes.
