in response to its "southern strategy" starting around 1970. Rural Democratic support has nevertheless persisted in union-influenced Roanoke in Southwest Virginia, college towns such as Charlottesville and Blacksburg, and the southeastern Black Belt Region. African Americans are the most reliable bloc of Democratic voters, but educational attainment and gender have also become strong indicators of political alignment, with the majority of women in Virginia supporting Democratic presidential candidates since 1980. International immigration and domestic migration into Virginia have also increased the proportion of eligible voters born outside the state from 44% in 1980 to 55% in 2019. State elections State elections in Virginia occur in odd-numbered years, with executive department elections occurring in years following U.S. presidential elections and Senate elections occurring in the years prior to presidential elections, as both have four-year terms. House of Delegates elections take place concurrent with each of those elections as members have two-year terms. National politics often play a role in state election outcomes, and Virginians have elected governors of the party opposite the U.S. president in eleven of the last twelve contests, with only Terry McAuliffe beating the trend in 2013. McAuliffe, a Democrat, was elected during Barack Obama's second presidential term. Republicans at that time held a supermajority of seats in the House of Delegates, which they had first gained in the 2011 state elections, and a one-vote majority the state senate, both of which they maintained in the 2015 elections. The 2011 and 2015 elections also had the lowest voter turnout in recent history, with just 28.6% and 29.1% of registered voters participating respectively. The 2017 state elections resulted in Democrats holding the three executive offices, with outgoing lieutenant governor Ralph Northam winning the governorship, Justin Fairfax elected lieutenant governor, and Mark Herring continuing as attorney general. In concurrent House of Delegates elections, Democrats flipped fifteen of the Republicans' previous sixteen-seat majority. Control of the House came down to a tied election in the 94th district, which the Republican won by a drawing of lots, giving the party a slim 51–49 majority in the 2018–19 legislative sessions. At this time, Virginia was ranked as having the most gerrymandered state legislature, as Republicans controlled the House with only 44.5% of the total vote. In 2019, federal courts found that eleven House district lines, including the 94th, were unconstitutionally drawn to discriminate against African Americans. Adjusted districts were used in the 2019
