Newsweek‘s Ryan Tracy tells us:

From 1998 to 2008, longtime Democratic Rep. Dennis Kucinich won each of his reelection campaigns by at least 49,000 votes. Even in the Democratic bloodbath that was the 2010 midterms, the former mayor of Cleveland and presidential candidate carried his district in northeast Ohio by a 16,000-vote margin, more than 8 percent. So why should he be worried about 2012?

Because it’s redistricting season again, the time when legislators redraw district boundaries based on new census data, and Republicans in Ohio are holding the pen. The Ohio GOP won the governor’s seat and took over the state legislature in the midterms, part of a nationwide statehouse surge that has placed Republicans in charge of redrawing congressional-district lines in 17 states, which account for a full 193 out of 435 seats in the House of Representatives, including all the seats from the swing states of Ohio, Pennsylvania, Michigan, and Wisconsin. Come 2011, the GOP will control more state legislatures than at any time since 1928. … the nationwide map holds little good news for Democrats when it comes to redistricting.
