The Republican establishment is said to have grave qualms about Texas Gov. Rick Perry’s presidential campaign. Here’s the problem: There is no Republican establishment. It squandered its authority by building up the Tea Party’s brigades and then fearing them too much to do anything to check their power.

Worse for those who think Perry would be a general-election disaster is the growing confidence among conservatives that President Obama will be easy to beat. This feeling will be bolstered by Tuesday’s special election that sent a Republican to Congress from New York’s 9th District for the first time since 1923. If Obama is going to lose anyway, many conservatives reason, why not go with their hearts?

No, if Perry is to be defeated, he will have to do the job himself. And the week’s most important political news is that he might do just that.
