Brooks is wrong, and the article is sloppy.
The nonsense starts in paragraph three:
Still, it is worth pointing out that this behavior is not entirely honorable. It’s not honorable to adjust your true nature in order to win re-election. It’s not honorable to kowtow to the extremes so you can preserve your political career.
What? I've read that paragraph about 5 times, and it makes less sense every time. How can someone adjust their true nature. If they flow with the current, well, that's their nature.
Furthermore, this idea that incumbents need to scramble in order to keep their seat (from a party challenger, no less) flies in the face of reality. The Republican establishment couldn't unseat Ron Paul from the inside, and they tried over and over again.
And then there's the cognitive dissonance in paragraph 5:
Republicans on the extreme ferociously attack their fellow party members. Those in the middle backpedal to avoid conflict. Republicans on the extreme are willing to lose elections in order to promote their principles. Those in the mainstream are quick to fudge their principles if it will help them get a short-term win.
Indicating that the latter (of the two last sentences) is better than the former, he completely argues against himself.
The next paragraph provides another gem:
In the 1960s and ’70s, the fight was between conservatives and moderates. Conservatives trounced the moderates and have driven them from the party. These days the fight is between the protesters and the professionals. The grass-roots protesters in the Tea Party and elsewhere have certain policy ideas, but they are not that different from the Republicans in the “establishment.”
Really? JBS type-ideology grew within the Republican Party during the 60s and 70s? What is he smoking?
I think he is trying to repackage one of the mantras from my early political science courses: that when a conservative is in the presidency, the congress moves to the left, and vice versa. While this has tended to be true, this is far different from what this guy is saying.
But the winner is the disgraceful last paragraph:
First they went after the Rockefeller Republicans, but I was not a Rockefeller Republican. Then they went after the compassionate conservatives, but I was not a compassionate conservative. Then they went after the mainstream conservatives, and there was no one left to speak for me.
Right, and the concentration camps are right around the corner..
