In December Romney held the opposite view, indicating that the federal government should be setting the limits for carbon emissions, a position in line with the domestic automakers. That however was before Michigan held its primary, which Romney won. It's not that McCain, Romney or any other candidate shouldn't support California's efforts. However, given their party's traditional recalcitrance on the issue, Romney in particular comes across as insincere at best. On air during the debate Romney agreed that states should be able to make their own decisions. Off-air when few people are likely to notice, the Romney campaign issued a statement that the federal government, not states, should set the limits.
