User blog comment:4. 1. 22. 5. M97/Blog Critic: "Why the Empire should prevail over the Stormcloaks" refuted (part1)/@comment-9062114-20140103232600/@comment-9062114-20140106060025

The Stormcloaks get numerous races joining them. As proven by dialogue from Redguard & Imperial farmers saying that they will join. In addition, Ulfric may want Great War vets fighting for him as opposed to just spell-swords and mercs.
