The Senate Leadership Fund is committing another $14 million to the Kansas Senate race as the Republican-aligned super PAC increases spending across several key contests ahead of the 2026 midterm elections.

The new Kansas reservation is part of $62 million in additional advertising the group has recently committed across Senate races, with much of the spending aimed at protecting Republican incumbents and strengthening the party's position in competitive states.

In Kansas, the money will support Republican Sen. Roger Marshall, with much of the spending expected to target his Democratic challenger, Adam Hamilton. Hamilton is a political newcomer and pastor who founded what has been described as the nation's largest United Methodist church.

Republicans have held Kansas' Senate seats for decades, and a Democrat has not won a Senate election in the state in nearly a century. President Donald Trump carried Kansas by 16 percentage points in 2024.

The Senate Leadership Fund is also increasing spending in several other races. In Maine, the group added $8 million for Republican Sen. Susan Collins, bringing its total reservations there to $50 million.

In Alaska, another $4 million is being added to support Republican Sen. Dan Sullivan against former Democratic Rep. Mary Peltola, bringing the group's total investment to $21 million.

Michigan's open Senate race is receiving an additional $2 million for former Republican Rep. Mike Rogers, bringing the group's total reservations in the state to $53 million.

The group previously added $20 million in Iowa, bringing its spending there to $53 million, and $14 million in Ohio, bringing its total to $93 million.

Trump carried Ohio by 11 points in 2024 and won Iowa and Alaska by 13 points each. The Kansas investment comes as Republican campaign groups assess where additional resources are needed during the closing stretch of the midterm campaign.

The Senate Leadership Fund also shifted some spending from North Carolina to Kansas last week. Democrat Roy Cooper is running against Republican Michael Whatley in North Carolina for the seat being vacated by retiring Republican Sen. Thom Tillis.

The spending changes come amid a political environment that has become more challenging for Republicans, according to Punchbowl News, which pointed to Trump's approval ratings and weaker enthusiasm among some GOP voters.

Two election forecasters currently rate the Kansas Senate race as leaning Republican, while both rate the North Carolina contest as leaning Democratic.
