President Obama "is working systematically to marginalize the most powerful forces behind the Republican Party, setting loose top White House officials to undermine conservatives in the media, business and lobbying worlds," Politico reports.
Among the White House targets: U.S. Chamber of Commerce, Rush Limbaugh, the insurance industry, Wall Street executives and Fox News.
"Obama aides are using their powerful White House platform, combined with techniques honed in the 2008 campaign, to cast some of the most powerful adversaries as out of the mainstream and their criticism as unworthy of serious discussion."
