I could support General Shinseki's replacement...
...if the replacement was a more effective leader of the VA than General Shinseki. Even an honorable and patriotic civil servant like General Shinseki would step aside to let a super-qualified individual manage and improve the VA.
But that's not what's happening here. What's happening is the most basic sham in the Republican political playbook: underfund a government program to the point it can no longer function, then demand a resignation of its manager, or whine the government agency is dysfunctional and should be replaced by private corporations doing the same job, but at even less efficiency.
What good is General Shinseki leaving if he would be replaced by a Republican political hack or corporation siphoning even more money away from patient care? Most veterans and Veterans organizations know the importance of effective leadership, and why they are opposed to the equivalent of a political coup at the VA
It's the oldest trick in the book.
