The dems lost due to 1 reason.
The moral bankruptcy of a sizable portion of the American electorate.
The bloated orange pedo tapped multiple veins of resentment in the US....
Misogyny
Racism
Transphobia
Wokeness
But what it came down to was the fact that wages have not kept up with inflation. This is not new. It has been happening ever since the GOP destroyed unions in the 70's. Cheap energy in the 80's and 90's hid the fact that wages were not keeping up due to outsourcing, right to work and union busting.
It was very easy to pin that on migrants who are willing to work and scrape by on minimum wage jobs that corporate america needed filled.
The democrats don't see that anger. They think by saying the GDP grew by X amount will placate the masses. It won't. America wants real change away from the plutocracy it is now.
It is hard to get people to believe they are better off as corporate america creates ever new methods to shift the cost of employment onto the workers. Pensions replaced by 401ks. Health insurance replaced by HMO's and then replaced with high deductible plans that drain the paychecks of workers and still leave them unable to afford to get sick. Instead of $10 copay from an HMO on a prescription, you get to chose to pay the first $7000 out of pocket or 50% or 40% or 60% of the retail cost of the prescription. But wait... you can now take up to $7000 from your paycheck to cover the high deductible AS WELL AS the increased insurance premiums lost in the word salad of bronze, silver and gold plans.
Fat nixon sold them the bill of goods that he was going to bring the cost of rent, food, gas, homes, etc without telling them how. The media when they asked about how would get a ten minute rambling explanation that ended up with talking about Hannibal Lecter from sundowning grandpa befuddlepant.
The people were dumb enough to believe him a second time.
Now the real pain is coming.
Donny Doll Hands is used to his whole life demanding to get what he wants when he wants it.
