If so, then this is a hopeful development. Note that Walker says he has been learning from Sen. Jeff Sessions on the issue.
The problem with Republicans focusing on illegal immigration as if it is only a law and order issue, rather than a existential issue for the GOP, is that it has taken focus off the arguably more important issue of the massive levels of legal immigration. At least illegal immigrants can’t vote so we’ll postpone Republican national irrelevance a generation until their birthright citizen children can vote. Legal immigrants can potentially become citizens and vote for Democrats this generation, thus consigning the GOP to national irrelevance even sooner.
I’m not going to support Walker, but I’m inclined to be less hostile to him now.
