In campaign news, voters head to the polls today in Michigan. In recent days, Republicans Mitt Romney and John McCain have fought over how to help protect the auto industry in Michigan, which has the highest unemployment rate in the country. Romney, who was born in Michigan, criticized efforts by McCain and other Washington politicians to make cars more fuel efficient.

Romney described stricter fuel standards as an unfunded mandate from Washington that will cripple the auto industry. Romney said, “Let’s take those burdens off and let our companies compete.” According to the New York Times, Romney has said little on the campaign trail about the potential dangers of climate change and almost nothing about curbing greenhouse emissions. McCain has called for capping gas emissions linked to global warming and higher fuel economy standards.
