The spending includes $15 million Pritzker put into his own political action committee, Ready for the Fight, which is airing ads in Tennessee, Arkansas, Alabama and Ohio. The rest has gone to campaigns and organizations involved in races for Congress, the Senate, governor and other offices, as well as ballot measures on abortion rights and redistricting.

Pritzker’s nationwide campaign activity comes as Democrats seek to gain ground in the Nov. 3 midterm elections. A Democratic-controlled House or Senate could also shape what a future Democratic president would be able to accomplish. Pritzker, a billionaire and heir to the Hyatt hotel fortune, is widely viewed as a potential 2028 presidential candidate, though he has not announced a bid.

His largest reported contributions this cycle include $1.5 million to the Wisconsin Democratic Party and $1.2 million to Gina Hinojosa’s Texas gubernatorial campaign. He gave $1 million apiece to the Democratic Governors Association, Senate Majority PAC, Ohio Democratic Party, House Majority PAC and Project Battleground, a committee supporting Georgia gubernatorial candidate Keisha Lance Bottoms. He also contributed $310,000 to the Democratic Senatorial Campaign Committee.

Pritzker has given $500,000 each to the Iowa and Michigan Democratic parties and $270,000 to the New Hampshire party. Other state party contributions include $150,000 in North Carolina, $125,000 in Georgia, and $100,000 apiece in Maine, South Carolina and Texas. New Hampshire and South Carolina are among the states that traditionally hold early presidential nominating contests.

He has also campaigned beyond Illinois. In August, Pritzker joined a voter canvass in Orlando with U.S. Rep. Maxwell Frost and Florida gubernatorial candidate David Jolly. He has headlined Democratic events and fundraisers across the country, including in several early-primary states.

Former Vermont Gov. Howard Dean, a former Democratic National Committee chair and presidential candidate, said Pritzker is among the possible contenders he is watching. Dean praised Pritzker’s record as a governor and described the donations as strategic investments, not simply acts of generosity.

Pritzker’s campaign says the money is directed toward races where additional support could make a difference, including campaigns that may be overlooked as donors concentrate on higher-profile contests. The governor also hopes his contributions encourage other donors to give, according to a person familiar with his spending.

Republican critics say Pritzker’s attention is focused too heavily on national politics. Illinois House Minority Leader Tony McCombie accused him of neglecting state concerns, while the campaign of Republican gubernatorial challenger Darren Bailey said Pritzker was trying to build political power for a presidential run. Pritzker is also campaigning for reelection against Bailey in the Nov. 3 governor’s race.

Pritzker’s wife, MK Pritzker, is a donor as well. She contributed $500,000 to Ohio Democratic gubernatorial candidate Amy Acton and publicly criticized an ad by Acton’s opponent, Vivek Ramaswamy. Illinois Lt. Gov. Juliana Stratton, who is running for the U.S. Senate, has also campaigned for Democratic candidates in other states.
