Should Conservatives Rethink Judicial Activism?

From George Will's latest column:

Conservatives spoiling for a fight should watch their language. The recent decision most dismaying to them was Kelo (2005), wherein the court upheld the constitutionality of a city government using its eminent domain power to seize property for the spurious "public use" of transferring it to wealthier interests who will pay higher taxes to the seizing government. Conservatives wish the court had been less deferential to elected local governments. (Stevens later expressed regret for his part in the Kelo ruling.)

The recent decision most pleasing to conservatives was this year's Citizens United, wherein the court overturned part of the McCain-Feingold campaign finance law. The four liberal justices deplored the conservatives' refusal to defer to Congress's expertise in regulating political speech.

So conservatives should rethink their rhetoric about "judicial activism." The proper question is: Will the nominee be actively enough engaged in protecting liberty from depredations perpetrated by popular sovereignty?
