Name a policy that helped his supporters. His policies either helped elites or hurt the other side, but did not help his base. Virtually the only thing he ever did for his own base was to give out COVID relief support.
Caging children at the border? All about hurting the other side that cares about immigrants.
Lowering corporate taxes? Help for elites, particularly for those with huge fortunes overseas. Workers saw virtually nothing from the tax cuts.
Stopping California from imposing stricter emissions standards? Help for elites.
Abortion? His side isn't having them anyway, it's all about hurting others.
Stopping student loan forgiveness? Either helping elites or hurting the other side. Maybe both.
Revoking the EPA's jurisdiction over waterways so that there is more pollution? Helping elites and hurting his side. Republican states are far more polluted than Democrat ones.
The trade war that particularly hurt farmers?
We could keep going like this. Virtually all of Trump's policies were designed to help elites, hurt the left, but not to help right.
The clearest way to put it, is the way his own supporters put it "He is hurting the wrong people." That's what Trump sells. It's a world divorced from reality where anyone who doesn't agree is an enemy.
Trump is not anti-elite. His supporters are not anti-elite. They love elites.
