"Conservatives have the ability to whip up an angry mob every time they disagree with a court case."
And liberals have a way of turning to the courts to overturn elections they disagree with, e.g. the governor's race in Washington state.
Judges seem to have a funny view of constitutionality. For example, consider free speech as defined by the First Amendment. Based on recent court rulings, they've made it more protected in some circumstances to spread pornography than political speech. Thanks a lot, John McCain.
If we want to avoid tyranny, no one branch of government can be exempt from criticism, checks and balances. Judges are no better than anyone else. Lord Acton's adage applies to them just the same as anyone else, "Power tends to corrupt, and absolute power corrupts absolutely."
