Colorado is poised to become the ninth state in the nation to allow lesbian and gay couples to form civil unions. After two years of fighting over the issue, the Republicans who controlled the House and killed the measure are out of power, paving the way for a civil unions bill to head to Gov. John Hickenlooper, who supports legal recognition for lesbian and gay couples. But the victory will be bittersweet for Sen. Pat Steadman, the gay lawmaker who has led the fight for civil unions. The Denver Democrat said he believes allowing gay couples to marry, rather than just form civil unions, would truly represent equality, but marriage equality is banned under Colorado's constitution.
