They want to cater to the 89% or whatever of the American public who want control of illegal immigration, and they want to cater to Latino voters.
Being savvy politicians who know what is most important to America, that being their own reelection, they have contrived an elegant tap dance. They ramble and they bloviate, they conjure up images of civil rights and the tired and huddled masses, and they expound upon their ramblings and bloviations. In short, they wax philosophical while saying nothing, exactly.
Their hope is that both sides, the border closers and the Latino hopefuls, will read in their ramblings and bloviations that hey, this guy is on our side.
They need to take a principled and enthusiastic position on one side or the other. It is not hard for me, a common nobody, to take a position. Why is it so hard for someone addicted to Washington DC? You either want to close the open border or you don't. There is plenty of time to consider issues such as separated families, good people vs bad people, economic pressures, perceptions of discrimination etc. All that in good time.
You either want to close the wide open borders, or you don't. Pick your side and weigh in.
Republicans need to do what is right. The other problems will then fall into place.
What is right?
Not giving amnesty to law breakers and building a secure border wall.
