George Will perhaps thinks too well of a certain segment of the Republican Party:

McCain hopes that in 2008 pro-life Republicans will remember his pro-life record. But they will know that, regarding presidents and abortion, what matters are Supreme Court nominees. McCain favors judges who think the Constitution is so radically elastic that government regulation of speech about itself is compatible with the First Amendment. So Republican primary voters will wonder: Can President McCain be counted on to nominate justices who would correct such constitutional elasticities as the court's discovery of a virtually unlimited right -- one unnoticed between 1787 and 1973 -- to abortion?

To be sure, McCain is no strict constructionist or textualist when it comes to the Constitution. No parchment, it seems, is sturdier in McCain's mind than his own iron-clad sense of right and wrong.

But how many Evangelical voters are constitutionalists? And how many just want to see abortion banned?
