The Democrats would totally do this.
They are the ones that started getting rid of the 60-vote threshold needed to break a filibuster, doing it in order to confirm lower-court judges. Then Republicans applied it to Supreme Court nominees. And now, President Trump says, it’s time to permit legislation to pass with just 51 votes, or 50 if the vice president is used as the tiebreaker in favor.

Perhaps the next step is another limited one, applying it just to spending bills. You can already pass what’s known as a “budget resolution” that provides a general blueprint for spending with 50 votes. How about the spending itself?
It’s the only way Trump will get $5 billion for his wall. Although it is possible Democrats will compromise if there is an extended shutdown and give him a portion of what he wants, even with the filibuster. But I doubt it.
