I see you are a good study of history. Most posters who claim to be good Republicans don't realize the "original" Republicans dislike war and government involvement at all stages.
You're right, I don't know who was a more determined pacifist, Fremont or Lincoln.
Lincoln was clearly a proponent of a small, non-intrusive government.
Student of history or not, I'm thinking you might be confusing the first Republicans with the Vallandigham/McClellan Democrats.
That's OK, it's been a long time.
