The Second Great Awakening was similar to Jacksonian democracy in its emphasis on what?

Both stressed the power and individualism in the common man.

Jackson supported and fought for the "common man" and tried to give power to the less wealthy, less elite people at the time. The Second Great Awakening emphasized religious and spiritual principles; it was a revival movement that reflected Romanticism, a European style that stressed imagination, emotion, and individualism. Both of these movements encouraged and supported common people.
