When Republican Senator Judd Gregg announced on Thursday that he no longer wished to be the Commerce Secretary nominee, he said that the decision was based in part on serious disagreements with the Obama White House over the 2010 census. That night on Fox News, Sean Hannity called Obama’s plans for the census process “the biggest White House power grab ever,” as his guest Karl Rove voiced agreement. The same day, House Republicans declared that the White House had “an unprecedented plan” for the census that “will taint results and open doors to massive waste of taxpayer funds.” It may sound surprising to those who don’t consider the decennial headcount a red-hot political matter, but the census has become the controversial subject of an ongoing power struggle between Democrats and Republicans.
