Jonah Goldberg writes in Townhall, Time to Grow Up, GOP, 1/16/13.
The good is obvious. The ill is less understood. For starters, the movement has an unhealthy share of hucksters eager to make money from stirring rage, paranoia and an ill-defined sense of betrayal with little concern for the real political success that can only come with persuading the unconverted.
A conservative journalist or activist can now make a decent living while never once bothering to persuade a liberal. Telling people only what they want to hear has become a vocation. Worse, it’s possible to be a rank-and-file conservative without once being exposed to a good liberal argument. Many liberals lived in such an ideological cocoon for decades, which is one reason conservatives won so many arguments early on. Having the right emulate that echo chamber helps no one.
It’s still good advice. It’s not that the GOP isn’t conservative enough, it’s that it isn’t tactically smart or persuasive enough to move the rest of the nation in a more conservative direction. Moreover, thanks in part to the myth that all that stands between conservatives and total victory is a philosophically pure GOP, party leaders suffer from a debilitating lack of trust — some of it well earned — from the rank and file.
But politics is about persuasion, and a party consumed by the need to prove its purity to its base is going to have a very hard time proving anything else to the rest of the country.
