McCain is set to tour the facility and lay out a plan to support innovation in the automobile industry - including a commitment to a $5,000 tax credit for each and every customer who buys a zero carbon emission car. The facility he is touring is where GM is developing the Chevy Volt - a hybrid gas-electric vehicle. He'll also lay out his plan for creating jobs in the industry, following the news GM will cease production at four North American plants by 2010.
Michigan, whose economy has been badly hit because of the struggling automobile sector, is likely to play a key role in the presidential election. The Arizona senator lost the state's Republican primary in January to Michigan native Mitt Romney.
