Perhaps Frum, in the words of John McLaughlin, "lurched uncontrollably into the truth", or perhaps his falling-out with Manor Bush and their Yankee-mandarin taskmasters and wannabee-Masters of the Universe has produced a demonstration of divine Providence, to use such a RiNO as Frum for a worthwhile cause.
Either way, the model/theory/excuse that let a generation of RiNO's cover up their swamping of the Republic with Orwellian masses of hungry Mexican immigrants is being gutted in Macy's storefront window.
Color me impressed.
PS: The Kirchner regime in Argentina is running the same sort of immigration policy. Black hearts think alike.
BTT
People forget his "Hard Right" phase which coincided with the 1994 Gingrich win. There may be some things Frum won't do, but most things are negotiable for him if it advances his career.
I was going to call BS on your anti-RINO diatribe, but in actual fact more Democrats did vote against the 1965 Immigration Act than Republicans.
So you're right: it's not something that the GOP moderates (which by today's standards included most of the party after Goldwater was defeated) can blame on Democrats alone.
But you will find that even Reagan didn't do much against even illegal immigration. The lure of cheap labor is a lot stronger than party or ideological divisions.
