The feds are coming for John Deere over the right to repair

What happens if the GOP wins in a couple of weeks? Would there be any way these actions can be sustainable for more than a few months?

Following the Reagan era, the GOP had a period of wanting to reign in the federal government, but I don't think that's quite true now. Folks like Trump or DeSantis are not pro-small-government, they just want to use it to advance different social policies. In the fight between farmers and Deere, I doubt they'd side with the company.

Trump’s VP nominee also completely flipped his views in the last few years to join the ranks of conservative grifters feeding off anti-immigrant and anti-“woke” sentiment. I wouldn’t trust anything he says.

The Trump/Vance admin will support whichever side they believe will benefit them financially, which won’t be the farmers.

The second statement does not follow from the first statement. You're suggesting that Trump will surround himself with sycophants based on him choosing as his running mate somebody who has publicly criticized him in the past.
