President Obama entered office hoping to bring us together. The Republican-majority Congress has not helped. Nevertheless, it was disappointing to read that “After White House, Obama to work on favorable redistricting for Democrats” [news, Oct. 18]. Apparently, Mr. Obama has given up on centrism. How many voters understand that less than 10 percent of seats are realistically up for grabs in normal House elections? Once you win a primary, you don’t have to worry about satisfying moderates, because true believers will carry you to victory.

If nonpartisan districting for the House had been in place over the past three elections, we would have heard already from the dissatisfied voices, left and right, and they might have had some degree of redress. Instead, thanks to gerrymandering, our election looks like an exploding pressure cooker. Ending gerrymandering is the best hope we have of bringing our troubled country a measure of peace.
