"For the second straight redistricting cycle, Republicans control the state legislature and governor's mansion and will be able to draw the new congressional district lines. Last time, in 2001, they tried to create a map on which they thought they could control as many as 13 or 14 of the state's 19 congressional districts.
But because they wanted to win so many seats, they left too many of their incumbents vulnerable, and by the 2008 election, Republicans controlled only seven of the 19 districts.
Big wins in 2010 mean Republicans are back on top and hold 12 districts in the Keystone State. But some Republicans say the lessons of 2001 have been learned, and priority number one in the 2011 round of redistricting will be to make sure their members are as safe as they can be."
