1. Both parties engage in and benefit from gerrymandering, the practice of redrawing district lines for partisan gain. In 2010, Republicans invested millions in statewide races to retake state legislatures for the purpose of controlling congressional redistricting. Since then, Republicans have created highly gerrymandered maps in states like North Carolina and Virginia. Democrats are guilty of gerrymandering as well: Maryland hosts some of the most contorted, gerrymandered districts in the country. Gerrymandering is one of the leading reasons that many congressional races are not competitive.
2. Both parties also thwart efforts to combat gerrymandering, such as amendments making gerrymandering illegal and the adoption of independent redistricting commissions. In Florida, where gerrymandering is outlawed by the state constitution, Democrat-sponsored bills to create an independent redistricting have led nowhere, and in Maryland, Democrats have been reluctant to give up control over redistricting after a commission appointed by the state’s Republican governor recommended handing mapmaking over to an independent panel.
