Abraham Lincoln Religion in Politics

[Gene C]

Salmon Chase seems to be Lincoln's biggest cabinet critic; Lincoln moved to slow, he was indecisive, he tolerated incompetence among his generals, and he was to slow in freeing the slaves with his actions not going far enough. Chase was very ambitious politically, and he burned a lot of bridges with political contacts. Most of these differences were based upon Chase's opinion that he would make a better President than Lincoln, and for the most part religion did not enter in to this side of his thinking. For Chase, freeing the slaves had as much to do with the constitution and the intent of it's framers as it did moral & religious values.
(a good resource is 'Salmon Chase' by John Niven and 'Team of Rivals' by Doris Kearns Goodwin)

I am not sure there was much friction with religious radicals among Lincoln's Cabinet.
