How the constitution is Dunn

Rep. Bill Dunn in the Tennessean on the constitutionality of the judicial selection process.

"Our government only has the power given to it from the people through the constitution. It is the people of Tennessee who have the final say in changing the constitution, not those in government. This raw power grab, if left unchallenged, emboldens those in power to seize more.
If election no longer means election, but instead means appointment, how could anyone argue constitutionally if legislation is passed that says the governor will appoint representatives and senators and then there will be a no-opponent retention vote in eight years?"
