I don't see how you're expecting things to work differently. Would we expect Democrat-sponsored legislation to fail for reasons apart from Republican opposition?

I doubt that is a true statement, but assuming it is then logically that would just mean that Republicans only propose legislation after they have talked to the Democrats and confirmed they are willing to vote it through. But that would suggest the Republicans are avoiding opportunities to kick up a fuss which doesn't sound like the US Congress we all know and love.

Unrelated note but it is amazing to me that the US has been an entity for a couple of centuries now and doesn't have legislation already in place to control the border.
