Well if the new Democrats (Marxists) win elections outside their curated big city collection of 9th generation welfare queens, 3rd world sh!thole imports and their sh!thole families with their sh!thole cultures, and blue haired nose ringed tatted females then yes I’d say the USA is in decline otherwise no. If you judge by Seattle, NYC, Chicago and pretty much all of California then I can see where the Chinese got that idea
"Much all of California" is not true, it's just the Liberal coast cities, most of the state is rural and conservative. Look at the election map sometime and see all of the red.
