The importance of this agreement is that once the bipartisan agreement is announced, it is another Trump shutdown should he block it. If he doesn't accept it, then he is right back in the same painful situation that caused him to cry uncle to Speaker Pelosi. If it goes even further, and a bill passes congress with bipartisan support and he vetoes it, then he starts the next shut down in much worse shape. We know Pelosi won't give and Trump will after he has dug a deeper hole for himself.
I don't want a shutdown, I want compromise that keeps the government open. But if the Democrats need to fight again to make it clear to Trump and the Republicans that shut down politics is bad politics, then the Democrats are starting with an even stronger hand this time.
