Trump's campaign platform was verbatim in favor of single family zoning according to his website. Harris's official platform was to ease permitting restrictions and provide incentives to states to reduce these regulations, according to their website and the multiple times they discussed this on the campaign trail.
Look past the marketing hype of DOGE and see that it's not actually deregulating anything that matters. The regulations that are blocking housing and energy are only going to be accelerated under this administration -- wilfully so.
The technocratic center-right have at times embraced deregulations like this, but not the new populist-right. The populist-right, if anything, see these regulations as useful because it empowers the immigrant scapegoat tactic as an explanation for housing costs.
