Cornered?
We'll see.
I sense the democrat-communists are prepared to hold out as long as it takes on this one, because they know this is the issue that will make -- or break -- the Trump presidency.
For this reason, I believe the best workable alternative is to go the "national emergency route" (the new caravan just starting out is a good justification to explain why it's needed), and start "building" the barrier without newly-approved Congressional funding.
Yes, it will result in court challenges or even a move for impeachment.
But if Mr. Trump wants to WIN on this one, that's a fight he'll have to face up to.
