While discussing the "new" fissures in the GOP over foreign policy (they're not, especially on Iraq and Afghanistan, but hey! Whatever), Alex Roarty at National Journal offers this:
But the shattering of that consensus isn't revealing new divisions within the party as much as laying bare old ones. Dating back to Sen. Henry Cabot Lodge, R-Mass.-who took on Democratic President Wilson over the League of Nations and won-an isolationist strain has always run through the party, even if it remained on the fringes. The more prominent battle within the GOP, however, has been between Republicans arguing for aggressive foreign intervention, as President Reagan did, or those wary of overseas involvement and promoting a more pragmatic view, like President Nixon.
