It is possible to hold a position on immigration that is principled, even if it is different from your position on the issue. Cruz on immigration is principled. Likewise Sanders is principled, even though he is wrong on most issues.

Principles don’t keep my family housed and fed. H-1B is a direct threat from a foreign invasion to artificially lower the prevailing wage of IT professionals.
