I don't think that's a great example. They have always been that way on immigration as far back as I can remember. Monstrous boarder policy has been the bipartisan consensus as long as I have been alive and probably longer.

The 2016 election was most demonstrative of this, being a race between "build that wall," and "comprehensive boarder security with physical barriers if nescecary" which isn't a difference in policy, but enthusiasm.

Immigration is great and we should try and negotiate a Schengen area style agreement with our neighbors. I have no representation.
