They barely bothered to campaign at all, despite wasting billions of dollars at the attempt.
Where do you get this from?
The Harris campaign was doing multiple rallies daily in swing states. You couldn't walk by a tv without seeing a campaign ad.
The bottom line is people preferred the Trump bullshit over the Harris truth.
Politesse isn't exactly wrong. The Harris campaign spent a lot of money convincing those who needed no convincing.
When I was a little kid, I had a misconception that being more "busy" in my action would get more done. The thing I didn't understand at the time was the concept of
wasted motion. I didn't know that I could do more while still accomplishing less of my goal.
Much of the issue here is that various conservative interests, and especially "covert" conservative interests such as the NYT, have an interest in forcing the Dems into "wasted effort", while giving "free effect" to the conservatives.
Is there an event that paints the Dems well or the conservatives badly? Publish stories about "congress"; the Dems have their victory diluted, and the conservatives have their sins piled on "government". In the inverse situation of shameful Dems or successful conservatives? Name them so that Dems are shamed and Cons are famed! Hire an editorial staff who will engineer headlines and influence the lowest information voters with the only thing they care about.
Rinse and repeat for an entire election cycle, and suddenly it doesn't matter how much spending is done on advertisements and announcements people actively avoid and ignore!
Social media? Twitter is literally owned by Musk, who has a finger on every scale in favor of Trump. Sinclair media owns an absurd number of local broadcasters across the nation.
The problem is that an ad can't compete with a firehose of scheduled content that says the opposite of what an ad does.
It wouldn't matter if the Dems spent 10 times as much, because those who own our media apparatus have a vested interest in countering and burying that message.
