It's one thing to be a rank-and-file surrender monkey, but when the Party leaders reveal themselves to be surrender monkeys, that's pathetic. They should have stuck with precedent.
I do wonder, though, if this action might not actually do more harm than good (for Schwarzenegger). First, it may cause a backlash among McClintock supporters. They may feel like they've been stabbed in the back and many may decide to sit out the election. Second, an official endorsement by the GOP tarnishes Schwarzenegger's "independent moderate" image by placing him squarely in the Republican camp. This may hurt his ability to "reach out" to Democrats and independents, some of whom may get scared off by this "official" GOP endorsement.
