Now imagine the first party comes back into power and goes ‘wow, thank god that will never happen again!’ twice more and does nothing to change the incredibly abuse-prone system, and you might have something approaching an analogy with context. Republicans are not the only party that has been in power since 9/11.

This is completely ignoring that historically ‘centrist’ (conservative) Democrats have championed their immigration stance as ‘common sense’, ie indistinguishable from their Republican opponents.
