The gag rule was favored mostly by _________.
The gag rule was favored the most by Southerners. The gag rule suppressed the discussion of petitions regarding slavery basically usually abolitionist petitions to abolish slavery in Washington, D.C. in the House of Representatives. Southerners were the gag rule's strongest supporters.
