Although he spoke on the topic only very briefly, Senator McCain's talk at CPAC hinted that a President McCain would make belief in judicial restraint a priority for his judicial appointments:

  [Clinton and Obama] will appoint to the federal bench judges who are intent on achieving political changes that the American people cannot be convinced to accept through the election of their representatives.
  I intend to nominate judges who have proven themselves worthy of our trust that they take as their sole responsibility the enforcement of laws made by the people's elected representatives, judges of the character and quality of Justices Roberts and Alito, judges who can be relied upon to respect the values of the people whose rights, laws and property they are sworn to defend.

More -- including an earlier address by McCain about judicial appointments -- from Ed Whelan.
