I admit I haven't really been paying attention to any of the ever shifting positions or rational after the first weekend. But just from the point of view of it being related to walls and wheels. Caving on wall funding to finish it isn't the worst move to make really, especially if they can bring the amount down by anything. It will take too long to get the process started, it's just a throw away of money on a vanity project anyway and everyone in the D camp knows its symbolic action more than anything real. And they can argue that it's worth the cost of restoring everything else if they need to.
Paying for a stupid wall is arguably a better deal than any kind of actual increased enforcement programs. And if they structure the funding right, they can basically punt it until 2020 and hope they win then kill it if they really need to. Plus a few House members can vote for it to use as cover. Maybe even some Senators. And that's just related to immigration/border security/whatever; an issue that only one party really cares about and will still go for the economy over.
Dragging it out in hopes of hurting Trump I think is a bit silly, he has a locked in group near 40% that seemingly won't abandon him, especially over his most important platform item. Congress has a built in 80% dislike rate no matter what they do. Bill and Barack wore down stronger Congresses because of this kind of power imbalance and they actually cared about maintaining their image some. Trump assumes he's invincible.
I like how they always seem to pick the dumbest thing on the table to shutdown over. Though it'll be hard to ever top Cruz's attempt at it over an already passed law, especially while shit talking his "allies" in the fight.
