Monroe County was chartered as a municipal corporation by the
New York State Legislature in 1892 and rechartered under New York's Municipal Home Rule Law in 1965. From
1856 to
1932, Monroe County voters voted for the
Republican candidate in every presidential election apart from
1912.
Democratic candidate
Woodrow Wilson was able to win the county in 1912 when the Republican vote was divided between then incumbent president
William Howard Taft and former president
Theodore Roosevelt. Monroe County voted for incumbent Democratic presidents
Franklin D. Roosevelt (
1936,
1940,
1944) and
Harry S. Truman (
1948). From
1952 to
1976, Monroe County voted for the Republican candidate in all presidential elections except for
Lyndon B. Johnson's Democratic landslide in
1964. In
1980, incumbent Democratic president
Jimmy Carter won Monroe County, despite having lost in the county to Republican
Gerald Ford in
1976. Monroe County went back to voting Republican in
1984 and
1988, but has voted for the Democratic presidential candidate every time from
1992 onwards, including the
2024 election. In 2020,
Joe Biden received the highest percentage of the vote for a Democrat since
Lyndon Johnson's 1964 landslide. In recent years, the urban area's traditional partisan dynamic appears to have begun shifting in the
Democratic Party's favor at the local level. A Democrat won the 2017 race for county sheriff for the first time in decades, in 2019 Democrat Adam Bello was elected county executive after over 30 years of Republican control, in 2020 democrats
Samra Brouk and
Jeremy Cooney flipped state senate districts long held by the GOP, and the traditionally Republican county legislature is now split 16–13 in favor of the Democratic Party. This matches a broader national trend of increased Democratic success in suburban areas.
Executive branch The county's executive branch is headed by the
county executive, Adam Bello. The executive's office is on the first floor of the county office building on West Main Street in Rochester. The county clerk is
Jamie Romeo, a Democrat. The county was exclusively governed by a board of supervisors for the first 114 years of its history. In 1935, the position of county manager, appointed by the board, was approved by popular referendum. In 1983, the position was replaced by a county executive, directly elected by popular vote, with expanded powers (e.g., veto). In 1993, the legislature enacted term limits for the executive office of 12 consecutive years to start in 1996.
Sheriff The Monroe County Sheriff's office (MCSO) provides law enforcement and has the constitutional authority to operate the county jail and provide civil functions. As with most counties in New York, the MCSO also performs a range of police services and provides physical and operational security to the courts. The MCSO is led by a
sheriff who is elected by the residents of Monroe County, serving a 4-year term. The sheriff is considered the highest
police official in the county, followed by an appointed
undersheriff and subordinate
chief deputy. The Monroe County Sheriff is Todd K. Baxter, a Democrat. Organizationally, the office is composed of numerous bureaus, each responsible for a given scope of functional operations. The jail bureau is the largest component of the sheriff's office, overseeing an inmate population of around 1,000. Under the New York State Constitution, the sheriff is the
warden of the county jail. The police bureau of the sheriff's office operates a sizable road patrol force which serves municipalities within Monroe County that do not independently enforce traffic. They are also responsible for primary police patrols at the
Greater Rochester International Airport and parks throughout the county. Deputies assigned to the marine unit patrol the coastline of
Lake Ontario as well as
Irondequoit Bay. The police bureau further employs a
mounted unit, bomb squad, SWAT team, hostage recovery, criminal investigations,
scuba, and
canine units. The court security bureau provides security at the Hall of Justice as well as at the
state appellate court building. In 2011, the uniforms were named the 2011 Public Safety Uniform Award in the County Sheriff's/Police Department category by the North American Association of Uniform Manufacturers and Distributors (NAUMD).
Legislative branch The county's legislative branch consists of a 29-member county legislature which replaced the earlier 43-member board of supervisors on January 1, 1967. Members meet in the legislative chambers on the fourth floor of the county office building. All 29 members of the legislature are elected from districts. There are 16
Democrats and 13
Republicans. The president of the legislature is Yversha Román, a Democrat. In 1993, the legislature enacted term limits of 10 consecutive years to start in 1996. Legislators can return to the office after not being in the legislature for a term. Since the enacting of term limits, as of 2024 four legislators (Stephanie Aldersley, Karla Boyce, Calvin Lee Jr., and Robert Colby) returned after previously leaving due to the term limit; Boyce was reelected again three times; Lee and Colby were appointed to fill vacancies before subsequently being reelected themselves; and Aldersley was appointed before being defeated for reelection.
