"Before the 2012 election, it was widely expected that the state legislature would gerrymander Barletta's district to make it safer for him. President Barack Obama carried the old 11th with 57%.[21] The new map, as expected, significantly altered the 11th. Heavily Democratic Scranton and Wilkes-Barre were shifted to the 17th District. To make up for the loss of population, the 11th absorbed some heavily Republican territory to the north and south that had previously been in the neighbouring 5th, 10th, 17th and 19th districts, pushing it as far south as the suburbs of Harrisburg. The new district is approximately ten points more Republican than its predecessor. Had it existed in 2008, President Obama would have only won 47 percent of the vote here to John McCain's 51 percent.[22] It appeared that the legislature wanted to protect Barletta by packing as many of northeast Pennsylvania's Democratic voters into the 17th as possible."
