The hashtags #Romneyencore and #47percent were both trending in the United States on Tuesday morning, helped along by users such as documentary filmmaker Michael Moore and comedian Chris Rock, whose "God Bless 47% of America!" tweet earned more than 5,000 re-tweets.

President Obama's campaign and the Democratic National Committee both pounced on the remarks, with David Axelrod mocking Romney's response to the video and DNC communications director Brad Woodhouse noting that there was nothing to "spin" in Romney's remarks.

Romney's team chose not to respond on Twitter to the controversy, instead letting the conversation run its course in the social sphere.
