With Republicans now controlling the governorships and legislatures in 25 states, the prospect for a conservative revolution is stronger than at any time in my lifetime. I am hopeful that Republicans in Washington will seize this opportunity to shift power and money back to the states, heeding the Tenth Amendment and fully harnessing the benefits of federalism. The state laboratories of government should have ample chance to innovate with scores of new ideas and policies to spark economic growth and improve education to lift people out of poverty and lift up the middle class.
