Thinking people might wonder why that is and why the democrats want this so badly.

I mean...it's not hard to figure that out? This is a must-pass, and Democrats control the Senate. They have a lot of leverage, so they've included a lot of stuff they want in the bill. As well as some stuff that GOP Senators want (like the disaster relief for NC that Thom Tillis insists have to be in the package). It's not really a deep mystery here.

The GOP can always say "no" to the Democrats and their Senate colleagues...but then they have to find the votes to pass a "clean" CR themselves. And they didn't have those votes previously (there are numerous hardcore GOP members who reject CR's on principle). So unless Trump and Musk can whip them from the left, which seems hard to do, the GOP won't have the votes to move Plan B either.

If they push into the next Congress, they gain control of the Senate, but have an even smaller House majority. So....they still need Democratic votes. And they'll be trying to do that while (presumably) trying to pick a new Speaker, manage the Trump transition over on the Senate side, and being moving on their early priorities (border, tax package, etc.).
