While Republican presidential candidate Sen. John McCain was visiting the
Technical Center in Warren MI on Friday he reversed direction on carbon dioxide regulation.
During a June campaign stop in Ohio
, McCain declared that he favored national standards for carbon dioxide regulation. While McCain was in Michigan he expressed support for state level rules to limit emissions. While there is nothing wrong in general with with learning new information and adjusting a position on an issue, Republican campaigners have a history of criticizing opponents for doing precisely that including in a new ad that was revealed the same day. An aide to McCain later tried to say that McCain only supported state level standards until a federal cap and trade system for emissions credits was in place. If McCain really supports the limits that California and other states are trying to impose than he should be doing his job in the senate and introducing a similar federal standard.
