renewable energy tax credits

Why did John McCain vote renewable energy tax credits, on 8 occasions?
I thought his brief, said it is for energy Renewable? Do they speak out or double talk? http://www.nytimes.com/2008/08/13/opinion/13friedman.html?em
Sorry, but in reality the McCain would not vote required to take a stand. Reread the article – which were not submitted to a vote of 8 times. On one such occasion was in its office and refused to come to the Senate. The man is a career politician to his core and can not speak. EDIT: For Cracker: Why is the government to give incentives tax the oil companies? As you say, if it is an economically viable industry, no need for them. So you're saying you're with Obama on this – you should remove the tax breaks and start taking some money back to help consumers? Now you're thinking right!
