You know the ones I have referred to here and with whom I have consulted myself and worked with myself -over the NEA, a handful of teachers and some parents with a history of drugging their children (see those people may have an agenda with which I disagree).
I am sort of... well.. "conservative that way". I am sure you understand, I just really prefer to respect the research of conservative think tanks and business folks over union leaders.
Conservative sources are good, but I always thought that conservatives based their opinions on the evidence, and liberals based theirs on "feelings". I like evidence.
