But a distinction without a practical difference. Neither state nor federal legislatures exercize their power of impeachment, especially not when the courts usurp the legislative function.
The people blame the courts, and the legislators duck the controversy. The public doesn't call on the legislators to exercise their power to impeach. In fact, I'll bet the public doesn't know the legislators even have that power. Or if they do, they perceive the power as being limited to removing drunk, incompetent and senile judges.
When I lived in California, we aborted Rose Bird and I believe we passed prop.13 on that same day...that was a nice election day.
In Minnesota we elect our judges but I guess they are appointed in other states. The people will demand that they vote for their judges in states where those judges are acting against the people and their elected reps aren't fixing the problem.
