Democrats and Republicans each have three party committees: a national committee to coordinate overall party objectives and one committee each dedicated to electing members to the Senate and House (referred to as Hill committees). During the 2018 campaign cycle, the six committees spent a combined $1.3 billion. So far in the 2020 cycle, they have spent a combined $1.8 billion out of more than $2 billion in fundraising.
