I wanted to give this part of Black’s post its own comment, because there was another interesting article I’ve been hanging onto for a week now that’s very important.

“This is insurrection and the pervasion of the immigration question, around 20 million people who entered the United States illegally, has corrupted the Democratic Party as its leaders balk at rational solutions. These include the establishment of a border, the deportation of serious law-breakers illegally present in the United States, a generous treatment for the people who entered blamelessly as children, and an expedited path to citizenship for the great majority of illegal entrants who have been constructive and law-abiding residents.”

It seems to me that most people outside the Beltway support all of these to some extent. However, because the Democrats have balked at securing the border and deporting criminals (or interdicting them before entry), the Republicans are wary of giving them the other two (having been burned before by putting generosity before security).
Trump won the immigration debate in the election because the rational people in the country could see that all four parts of the solution have to go together.

“The nadir of the amoral egotism of what might broadly be called “Me-ism” has been reached by the avant garde of the Democratic Party in their race to the bottom of the electoral depths. The renunciation of any notions of sacrifice, patriotic pride, the spirituality of life, or the recognition of anything except the smash-and-grab politics of endless atomized grievances and instant gratification of convenience, has reached what must, in its way, be the end of history.”

Cogent commentary? Or mere wishful thinking?… Key graf:
“…Faced with a Trump they could not defeat and cannot destroy, Democrats appear to be entering a frenzy of primal extremism. If the Democrats go to the voters next year as the party of infanticide, open borders, a 70 percent top personal income tax rate, and the practical abolition of private health care, they will vanish more quickly, and with less distinction, than the Whigs….”

Candidate Trump plans to give voters a remake of Ronald Reagan’s morning in America, while the Democrats are offering a nightmare on Elm Street. The optimistic Reagan vision—which was FDR’s and JFK’s—always wins that competition. By default, the whining Democrats have let dour Donald Trump present himself as the country’s Mr. Sunshine.
