four times), Howard W. Jackson, William F. Broening, and Theodore R. McKeldin. The mayor was originally elected to a term of two years under the original City Charter of 1796–1797. In 1920, the charter was amended so the mayor serves a term of four years. There are no limits on the number of terms a mayor may serve. For years, the mayor was elected in the year immediately preceding the presidential election. However, in 2012, the 2015 election was postponed to 2016 in order to better align with national elections. As a result, incumbent Stephanie Rawlings-Blake had her term extended an additional year. An earlier attempt to move the mayoral election to the same year as presidential elections was made in 1999, but went awry when the General Assembly refused to move the primary election. As a result, then-incumbent Martin O'Malley was nominated for a second term in 2003, then had to wait over a year to run in and win the general election. Baltimore has experienced major turnover in the mayor's office in recent years, in large part due to corruption scandals. In September 2015, incumbent mayor Stephanie Rawlings-Blake announced she would not seek re-election, setting up a hotly-contested primary election in the heavily Democratic city in 2016. Maryland State Senator Catherine Pugh defeated former mayor Shelia Dixon, who resigned from office in 2010 after pleading guilty to misappropriating holiday gift cards intended to serve poor Baltimore residents. Pugh easily defeated Republican Alan Walden and Green Party candidate Joshua Harris to become the 50th Mayor of Baltimore, and was sworn in on December 6, 2016. Pugh resigned on May 2, 2019, amid a scandal in which Pugh was accused of, and eventually pled guilty to charges of fraud, conspiracy, and tax evasion regarding a scheme to sell copies of a self-published children's book series, known as Healthy Holly, to the University of Maryland Medical System without competition. Upon Pugh's resignation, then-City Council President Jack Young took over as Mayor. In the 2020 Democratic primary, Young went up against Dixon, his successor as City Council President Brandon Scott, former T. Rowe Price executive and Obama Administration Treasury Department official Mary Miller, former federal prosecutor and deputy Attorney General of Maryland Thiruvendran Vignarajah. Scott narrowly edged out Dixon, with Young finishing a distant fifth. Brandon Scott was elected with more than 70% of the vote in the November general election, and
