Considering that almost all discussion of immigration for the 20+ years prior to Trump's election (even by most allegedly conservative Republicans) has focused on how to increase immigration quotas and how to legalize those here illegally, these small steps are already a vast improvement.
Correct, BOTH parties have been fully committed to the GHW Bush Plan for North Mexico (aka USA).
The final amnesty that would cement it in place has eluded them since 2006.
They sold US Rubio for the last attempt in 2013.
It was only US Cantorizing the weasel Eric Cantor that stopped them.
