From its headquarters in Columbus, the Republican Senate Campaign Committee (RSCC) operates a full-time, year-round operation that manages every aspect of a legislative campaign effort.

Republicans first gained majority control of the Ohio Senate in 1984, during the landslide re-election of President Ronald Reagan, who carried 49 states that year, and amid growing dissatisfaction with Ohio’s Democrat-controlled legislature. The previous year, Senate Democrats approved a 90 percent tax increase to address a massive budget shortfall, prompting voters to hand the Senate majority to Republicans—a majority they have maintained ever since.

Despite changes in political control of the Governor’s office and the Ohio House of Representatives over the decades, the Ohio Senate has remained a Republican stronghold, serving as a check against policies that could move Ohio in the wrong direction.

In 2024, under the leadership of President Rob McColley and others, Republicans once again maintained supermajority status in the Ohio Senate. With a skilled team operating statewide, RSCC has become one of the nation’s most respected legislative political organizations, continually adopting the latest campaign technology and strategies.

Statement from Senate President Rob McColley

“The Republican Senate Campaign Committee (RSCC) stands as the sole organization dedicated to safeguarding and expanding the Republican majority in the Ohio Senate. With the unwavering support of our dedicated donors and the tireless efforts of our exceptional candidates, RSCC is poised to uphold our tradition of excellence and ensure a prosperous future for Ohio.”
