Ask yourself: "Why am I permitting politicians to choose who their voters are, when I should be choosing who will represent me?" Politicians in Pennsylvania on both sides of the aisle have corrupted the process of redistricting to ensure re-election and suppress competition. Consider the graphic below (from Fair Districts PA site) of Pennsylvania's 7th congressional district. Beyond defying common sense, it results in ineffective representation and destroying the franchise to vote.
I completely support the non-partisan initiatives currently before the Pennsylvania House and Senate to establish an independent commission to control the redistricting process and return the choice to the voters.
