Pritzker formally announced his candidacy for the Democratic nomination for governor of Illinois on April 6, 2017. He built a broad coalition of support, earning endorsements from Illinois Secretary of State Jesse White, Congressman Luis Gutiérrez, more than a dozen members of the Illinois General Assembly, 21 local labor unions, and the Illinois AFL–CIO. In August 2017, he selected freshman state representative Juliana Stratton as his running mate.
He won the Democratic primary on March 20, 2018, capturing 45.13 percent of the vote. During the campaign, he spent $171.5 million of his own money on digital outreach, television advertising, and staff, making it one of the most expensive self-funded campaigns in state history.

He was inaugurated as the 43rd governor of Illinois on January 14, 2019.
First Term Achievements (2019–2023)
During his first term, Pritzker signed into law several landmark pieces of legislation. On June 25, 2019, he signed the Illinois Cannabis Regulation and Tax Act, making Illinois the 11th U.S. state to legalize recreational cannabis, with sales beginning January 1, 2020. Earlier that year, he signed a bill raising the state minimum wage to $15 an hour by 2025, making Illinois the first state in the Midwest to reach that threshold. He also signed the Fair Tax constitutional amendment, expanded reproductive rights through executive action, and joined the United States Climate Alliance.
In June 2019, Pritzker signed the bipartisan $45 billion Rebuild Illinois capital plan, the state’s first major infrastructure bill in a decade. The same year, he enacted a statewide response to the COVID-19 pandemic, including school closures, stay-at-home orders, and the five-phase Restore Illinois reopening plan. His administration also banned private immigration detention centers, raised the legal smoking age to 21, and signed an assault weapons ban in January 2023.
Second Term and Reelection (2022–Present)
On July 19, 2021, Pritzker confirmed he would seek a second term, again selecting Juliana Stratton as his running mate. He won the June 28 Democratic primary and defeated Republican nominee Darren Bailey in the November 8, 2022 general election, 54.91 percent to 42.37 percent. He is the first Illinois governor elected to a second term since 2006 and, if he serves two full terms, will be the first Democratic governor in state history to do so. His second term began on January 9, 2023.
Since his reelection, Pritzker has continued to focus on criminal justice reform, clean energy investment, and reproductive rights. In 2025, he signed the Illinois House Bill 1697, the Prescription Drug Affordability Act, which passed with bipartisan support. He has also emerged as a leading national voice in the Democratic Party and was mentioned as a possible running mate for Vice President Kamala Harris in 2024, though Minnesota Governor Tim Walz was ultimately selected.
Notable Events and Milestones
One of the defining moments of Pritzker’s tenure came in 2019, when he signed the Illinois Cannabis Regulation and Tax Act and later pardoned more than 20,000 people for low-level cannabis convictions. By the end of 2024, Illinois cannabis sales had reached $2 billion, generating roughly $490 million in tax revenue. His signing of the 2023 assault weapons ban, later upheld by the Illinois Supreme Court, marked another signature legislative achievement of his governorship.
