On the VDARE.com blog, Peter Brimelow suggests:
Obama and the Democrats can easily break this [Palin] momentum. All Obama has to do is ask John McCain (who, despite appearances, is still the GOP presidential nominee) to pledge, in the spirit of the “bipartisanship” that McCain was going on about Thursday night, that they will both work together for amnesty in the next Congress, regardless of which of them goes to the White House and which of them remains in the U.S. Senate.
McCain would be really stuck. He can’t refuse because (a) he really wants an amnesty and was fanatically committed to the Kennedy-Bush version; (b) he actually believes all this innumerate nonsense about the Hispanic vote.
But he can’t agree because that will utterly dispel the delusions of his desperate base.
Obama could specifically offer McCain an agreement in which they both pledge to work together to pass in 2009 the Secure America and Orderly Immigration Act (S. 1033), which was proposed by John McCain.
"The comprehensive immigration reform bill that Senator McCain wrote with Senator Kennedy is not entirely to my taste, but I'm willing to put up with the parts of Senator McCain's amnesty plan that I don't like so that we can be sure something finally gets done. After all, I have to admit that Senator McCain has worked far harder over the last four years to provide amnesty to illegal aliens than I have. Therefore, to break the logjam in Washington, I'll offer to take his word for it that the McCain-Kennedy amnesty bill is the right approach to amnesty. Clearly, Senator McCain is the expert on amnesty, not me. Giving amnesty to illegal aliens undoubtedly means more to him than, to be frank, amnesty means to me, so I'm willing, if he's willing, to pledge to pass his illegal immigrant legalization bill, which -- did I mention? -- he wrote."
If McCain replies that he's no longer for his bill, Obama could say with a puzzled look on his face, "Oh, so you were for it before you were against it? I see ..." and nod his head slowly, while scratching his chin, furrowing his brow and biting his lip in a thoughtful manner. Then, suddenly (and, preferably, with Franklin Roosevelt's Mid-Atlantic accent), "But, aren't we talking about your own bill? If it is a bad bill, why did you propose it? If it is a good bill, why are you against it?"
FDR could have gone on in this disingenuously ingenuous vein for weeks, having a grand old time at his rival's expense while the Republican base's enthusiasm for its nominee collapses, but, somehow, I don't think Obama can bring himself to play dumb, even to get elected President.
