(Harrisburg) -- State lawmakers have started the legislative redistricting process with a vote to approve the latest U.S. Census data as the basis for new district boundaries. The green light comes in spite of a small, potential problem. Lawmakers on the panel agree: it’s a tiny issue, more theoretical than practical. About 125 of the more than 9,000 precincts in the state don’t seem to line up well with Census data. The two grids don’t always match, so it’s tough to decide whether people living in the left-over fragments go to one district precinct or another. Erik Arneson, spokesman for Senate Majority Leader Dominic Pileggi, says geography accounts for that -- municipalities don’t tend to fit neatly into squares. "Even the county shapes, are you know, Centre County looks like wood woodpecker’s head. We have some very interesting geographic features in this state," he says. "It’s fantastic, but it leads to some odd-looking outlines, no matter how you draw." Lawmakers have voted to try to reconcile the boundaries as they work on new district lines. They now have 90 days to submit a rough draft of their plan.
