"Trump’s apparent campaign to tilt the playing field can be broken down into three main categories: rigging elections, controlling the referees, and disabling the opposition."
The Trump administration seems to be enacting “a long-term strategy to change the norms of political engagement in America,” Paul Rosenzweig argues. The president’s apparent campaign can be broken down into three main categories:
Tilting the Playing Field
Trump and his allies seem to want to transform American politics into a system for producing Republican victory.

A record number of Americans are behind on their auto loans
Last month, 6.65% of subprime borrowers were at least 60 days late on their car payments. That’s the highest delinquency rate since the 1990s, according to Fitch Ratings.

The human suffering is bad, but I also just hate the confident, based-on-nothing prediction that drives policy.
I spend stupid amount of time trying to quantify plausible effect ranges for policies just to get to "idk" and the people holding the levers of power are just like "homelessness is over"

I’m thinking that US voters being “furious about prices” when Trump’s fascist regime are attacking democracy, human rights, the environment & climate, public health, the global economy, the sovereignty of nations, a sane world order, and more, may be why the world will never trust U.S. voters again.
Americans are upset about prices & things are completely unraveling for Trump.
Americans were upset about prices under Biden & his poll numbers were like Trump's are now.
Americans were upset about prices when @kamalaharris.com ran & she nearly won. Says a lot about her strength as a candidate.

Hey winter cyclists: the smartest thing I've done after threatening to do it for too many years was actually write down what to wear based on temperature. This helped immensely last year, and winter is coming 🥶

The light rail train on 4th seen passing in front of this roboherd has more passenger capacity than all of them combined.
