incumbents all around the world have performed terribly post COVID. UK, Canada, Japan, France, Italy, have all had landslide or shocking election results. Unsure what the general mood is that can lead to Keir Starmer dropping 30 points in approval months after winning in a landslide, but the mood of general discontent may be relevant in the United States as well. It seems whatever the status quo / incumbent advantage…
The reason for this isn't a mystery: the world doesn't work for the plurality of its populace. The current generations were sold a lie of infinite prosperity and comforts by their elders and governments, a lie built on the exploitation of former colonies and underdeveloped nations. We see the lie now, and know it cannot be sustained in the face of our current polycrisis (climate, housing, necessities) simply by promoting infinite growth. There's an understanding that we need to curtail consumption and start properly engineering a global economy rather than letting it spawn and mutate naturally, but there's still enough people out there who believe that this demagogue, this partisan, this policy will give them the riches and posh comforts their elders enjoyed, thus returning their country to a golden era that never really existed.
It's the desperation of the masses for what they feel is rightfully theirs, because that's what they were told by those who pulled up the ladder behind them. That era is long gone, but nostalgia is a powerful force that's easily propagandized by those who benefit from said desperation.
