According to the nonpartisan Center for Responsive Politics, Republicans receive far more campaign money from the oil and gas industry than do Democrats.
So far in 2010, the oil and gas industries have contributed $12.8 million to all candidates, with 71% of that money going to Republicans. During the 2008 election cycle, 77% of the industry's $35.6 million in contributions went to Republicans, and in the 2008 presidential contest, Republican candidate Sen. John McCain received more than twice as much money from the oil and gas industries as Obama: McCain collected $2.4 million; Obama, $898,000.
This is a decades-long trend, the center says: Since 1990, oil and gas companies have donated $238.7 million to candidates and parties, with 75% of the money going to Republicans.
