John Hood notes that the conservative civil libertarian group American Freedom Agenda is going after GOP contenders who won’t pledge to uphold habeas corpus and judicial oversight of domestic surveillance, with Mitt Romney first in their sights. I’d love to see this pick up steam. If it doesn’t, a more sober generation of Republicans may regret having allowed basic respect for fundamental constitutional principles to be cast as the unique province of the Democratic Party. In related news, it’s good to see Colin Powell calling for Gitmo’s closure.
