You are correct that major legal changes in the immigration process generally require bipartisan support. However, controlling the executive branch is already sufficient to sabotage the implementation of the existing laws. In 1986 the US passed a bipartisan compromise bill that naturalized illegal immigrants residing in the US in return for measures that were supposed to prevent further illegal immigration. However, subsequent Democratic administrations largely refused to enforce them allowing illegal immigration to grow. There is no obvious reason to think that the recent bill proposed by Democrats would have been any different. Given that it was proposed during the election year, its only effect would have been to allow Democrats to pretend that the issue has been resolved and remove it as a discussion topic during the election campaign.
The bill was a bipartisan bill though. As described by republican James Lankford:
It is interesting: Republicans, four months ago, would not give funding for Ukraine, for Israel and for our southern border because we demanded changes in policy, [..] And now, it’s interesting, a few months later, when we’re finally getting to the end, they’re like, ‘Oh, just kidding, I actually don’t want a change in law because it’s a presidential election year.’
It’s effect would have been to improve the border. That’s why there were republicans who wanted it passed, because they wanted to improve the border. Some democrats probably also want to improve the border, while some democrats just want to pass the bill to improve the chances that the democrats would be elected again. But the republicans probably don’t want the democrats to win, and probably just wanted to pass the bipartisan border bill to improve the border.
