I think Brooks is right -- which is great news for Democrats:

In sum, Republicans know they need to change, but they have closed off all the avenues for change.

The tale is not entirely hopeless. McCain seems now to be throwing off his yoke. Newt Gingrich is way ahead of his colleagues when it comes to new ideas and policies. The libertarians and paleoconservatives have been losing for so long they are suddenly quite interesting. There are even a few of us who think it is time to revive the Alexander Hamilton-Theodore Roosevelt legacy.

Change could, miraculously, come soon. But the odds are it will take a few more crushing defeats before Republicans tear down the self-imposed walls that confine them.

Grim Old Party

At the University of Chicago there’s a group of scholars who are members of what is called the Rational Expectations school of economics. They believe human beings tend to anticipate unpleasant future events and seek in advance to avoid them. Their teachings do not apply to the Republican Party.

The Republicans suffered one unpleasant event in November 2006, and they are headed toward an even nastier one in 2008. The Democrats have opened up a wide advantage in party identification and are crushing the G.O.P. among voters under 30.

Moreover, there has been a clear shift, in poll after poll, away from Republican positions on social issues and on attitudes toward government. Democratic approaches are favored on almost all domestic, tax and fiscal issues, and even on foreign affairs.

The public, in short, wants change.
