It is true.
Frank Luntz - Wikipedia, the free encyclopedia
Luntz is not just a pollster. He's a consultant on the use of language in political campaigns, and a political strategist. While he is not officially affiliated with either party, all his work in U.S. politics is for Republicans. He is considered an expert in the field, and so when he says he takes Occupy seriously and is "scared" of it, that's an important indicator that the movement is shaping how people think.
While I consider Luntz a prime scumbucket, I recognize his abilities in his chosen field, as should everyone.
