With what, a snap of the fingers?
David Frum, the author of the article at the top of the thread, is a former speechwriter for President Bush and wrote The Right Man: The Surprise Presidency of George W. Bush.
He's warning of the threat Bush's illegal alien policy poses to the GOP with good reason: it's very unpopular and pisses people off.
That is one pundit's opinion, I disagree with it, I think that Bush's proposal puts some sanity into the system that has gone haywire after festering for 40 years.
OH BTW, Frum also writes for the New York Times(i.e token conservative), what better way to keep a paycheck from the NYT than write a wedge article. Granted it's during a slow time and not in the NYT, a wedge article none the less, to put on his resume to keep Pinch Sulzberger happy.
The anti-Mexican fusilades and theatrics are approximate modern day equivalents of the "Rum, Romanism and Rebellion" anti-Irish Know-Nothingism and stupidity of the 1880s GOP which delayed the journey of the Irish to the GOP by about 90 years.
Also, your diagnosis of Frum's argument seems at odds with his rendition on C-SPAN this morning. We are dealing with an issue---not a crisis of Biblical proportions. One solution is that people who seek freedom should be prepared to offer it. Offering that freedom to others may piss some people off, as you put it. That does not mean that the GOP should pander to people simply because they are pissed off. We aren't re-running the Ohio presidential vote of 2004 or the Florida presidential vote of 2000 either no matter how many delusionals are "pissed off."
Also anyone imagining himself or herself as a conservative but clinging to Border Obsessives for Hillary!!!!! as a guideline for 2008 and succeeduing at electing her will get the government (and ten times more of it than necessary) that he or she deserves. It Takes a Village to Do Your Hair, Cut Your Lawn, Decide What You Want for Lunch and Everything Else; It Takes the Demonratic National Committee to Set your Tax Rates; It Takes Al Qaeda to Run the State Department; Anti-Faith Based Social Programs and Re-Education Camps; etc.; etc.; etc.; ad infinitum et incarceratum ad nauseam.
