Obama strategy: Marginalize most powerful critics

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.

With a series of private meetings and public taunts, the White House has targeted the U.S. Chamber of Commerce, the biggest-spending pro-business lobbying group in the country; Rush Limbaugh, the country’s most-listened-to conservative commentator; and now, with a new volley of combative rhetoric in recent days, 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.
