From the Fix:
Rep. Tom Tancredo (Colo.) today ended his long-shot bid for the 2008 GOP presidential nomination and threw his support to Mitt Romney.
Tancredo's biggest impact on the field came as he bowed out of a contest that he never had any real chance of winning. Tancredo had made tough stand on immigration the centerpiece and organizing principle of his campaign, and his endorsement of Romney could prove a powerful validator of the former governor's bona fides on the issue.
