The coming debate in the Colorado House Judiciary Committee on same-sex civil unions bill SB 172 will center on Republican arguments for and against the legislation. The debate scheduled to take place under the Dome in Denver Thursday will underline the dynamics shaping the larger national debate on gay rights– a debate that now pits Republicans against Republicans because Democrats and Independents have already made up their minds on the matter. As expected, Denver Senator Pat Steadman’s bill passed out of the Democratic-controlled Senate late last week.
