Party won the majority of the seats in the House of Representatives, gaining a net total of 41 seats from two years prior, their largest gain of House seats in an election since the 1974 elections. On November 28, 2018, the Republican Main Street Caucus met with the Republican Main Street Partnership to ask why the Partnership's SuperPAC still had $722,000 unspent, rather than spending that money on competitive races to keep its members in office. The Partnership's chief executive officer, Sarah Chamberlain, said that $6million had been spent on 2018 campaigns, and that the remaining $722,000 was set aside for 2020. Members of the Caucus were concerned that Chamberlain's compensation was 20percent of the Partnership's operating expenses. The following month, the Caucus asked Chamberlain how the Caucus had spent its money to help its members' races. Chamberlain referenced an organization, Women2Women, that was part of the Partnership's network that many Caucus members had never heard of, spurring questions about Chamberlain's leadership. The Caucus voted unanimously to suspend political activity with the Partnership until an independent audit of the Partnership's governance could be conducted. The Partnership declined to be audited, saying it was a private organization, independent of the Caucus, and that the Caucus had no right to request an audit. The members of the Caucus voted to dissolve itself in February 2019. Some of its members decided to join the bipartisan Problem Solvers Caucus. The Partnership continues to exist.
