Both pro and anti amendment groups formed to sway voters. The "Don't Amend Alliance" organized in spring, much earlier than pro-amendment groups. The Alliance raised hundreds of thousands of dollars, catching supporters of the amendment by surprise. They responded with the "Yes! For Marriage" group, which only began a coordinated campaign on October 5. Nonetheless, latent support for the amendment appeared high with over 60% support for the Amendment in a Salt Lake Tribune poll conducted early October.
