In today’s column, conservative writer David Brooks wonders whether the Republican Party has lately gone off the deep end, having been “been infected by a faction that is more of a psychological protest than a practical, governing alternative.”

… The members of this movement do not accept the legitimacy of scholars and intellectual authorities. A thousand impartial experts may tell them that a default on the debt would have calamitous effects, far worse than raising tax revenues a bit. But the members of this movement refuse to believe it.

The members of this movement have no sense of moral decency. A nation makes a sacred pledge to pay the money back when it borrows money. But the members of this movement talk blandly of default and are willing to stain their nation’s honor.

The members of this movement have no economic theory worthy of the name.

… If the debt ceiling talks fail, independents voters will see that Democrats were willing to compromise but Republicans were not. If responsible Republicans don’t take control, independents will conclude that Republican fanaticism caused this default. They will conclude that Republicans are not fit to govern.

And they will be right.
