L vs J on education, part trois

I don't see Obama's election time support from teacher's unions as a major incentive for Obama to pick a Secretary of Education with conventional views. Particularly in light of what is happening in the auto industry, I see the power of big unions further falling out of favor with the American public. Mind you, a majority of the people in Detroit no less, support allowing the Big Three to fail. If anyone other than David Brooks cares about Obama's pick for Secretary of Education, will the same argument be made that going against the teacher's unions for the good of our children is the same as forcing the auto unions to make concessions for the good of our economy?
