Washington (CNN) - Rep. Patrick McHenry, R-North Carolina, has a message for fellow conservatives on National Census Day: "I'm worried about this year's census."
In a post Thursday on the conservative Web site RedState, McHenry expressed concerns about "blatant misinformation" about the census "coming from otherwise well-meaning conservatives." Some on the right have claimed that the census is unconstitutional, he wrote. Others fear that its results will be politicized by the Obama administration.
"They are trying to do the right thing," McHenry wrote, "but instead they are helping big government liberals by discouraging fellow conservatives from filling out their census forms."
McHenry warned that low participation among conservatives could result in Democrats having a big advantage in the next round of congressional re-districting.
"Few things make will make Nancy Pelosi happier than large numbers of conservatives failing to respond to the census," he wrote. "If we do not respond, we will not be counted and if we are not counted, then we effectively will not exist."
McHenry was one of three GOP congressmen who rebuked Rep. Michele Bachmann, R-Minnesota, last year when she urged conservatives to avoid filling out their entire census form. She said at the time that it would be unconstitutional to provide any information other than basic family details.
In his RedState post, McHenry told conservatives to avoid leaving any questions blank.
"No one has advocated a direct boycott of the census but there have been calls to only partially fill out census forms – even though that would be a direct violation of federal law," he wrote. "Those calls are the problem."
