I saw an interview with Trump and he said something that was actually partially correct! He was asked how he'd combat inflation and he said "Day 1 we'd start drilling, then people wouldn't be able to price gouge because there wouldn't be any scarcity."
While it's clear that drilling for more oil & gas would increase supply, and that all else equal prices do go up if there is scarcity, I'm not sure why he thinks that increasing oil supply will magically increase the supply of all goods and services. He did say something about "incentivizing production" which would indeed work, but he didn't propose anything concrete, contrast to Harris which, whether you like the proposal details or not, presented a plan to incentivize home production.
(In the same interview he said his policies would reduce energy prices by 50%, and also that if Harris' tax plans take effect that a middle-class tax bill would likely quadruple. The only way I can think of a tax bill quadrupling is if you are presently sitting very close to the zero tax level, basically just over the standard deduction. So while maybe true in some specific corner cases, I doubt it would be true for the "average" taxpayer.
Oh also Trump somehow thinks that deporting 15-20 million immigrants would somehow not be inflationary, because I'm sure the remaining population will accept whatever abusively low wages those folks were making, and we also wouldn't have labor and therefore product/service shortages.)
