As the U.S. goes through one of the most contentious midterms in recent years, the amount of spending in the 2018 election is setting records -- both in individual races and overall.

Election overview

According to a projection based on the Center for Responsive Politics' analysis of Federal Election Commission reports, the total amount of money spent on congressional races in this election cycle is expected to reach $5.2 billion, a 35 percent increase from the 2014 midterms.

This includes money spent by candidate campaigns, party committees and various outside groups. With a total of 1,661 Democratic House and Senate candidates and 1,471 Republican candidates, so far, a total of $1.26 billion has come from the Democratic side and a little shy of $890 million has come from the Republican side.

More than $1.3 billion in outside spending has come from more than 3,200 outside groups, including party committees, super PACs and political nonprofits, marking a 60 percent increase from 2014.

    In Florida, the Senate race between Democrat Bill Nelson and Republican Rick Scott has brought in more than $181 million. More than $91 million of that has come from the two candidates, with challenger Scott outspending Nelson by more than $40 million. The Democratic leadership has jumped in to back Nelson, with major Democratic outside groups spending more than $53 million in support of Nelson and against Scott. Meanwhile, New Republican PAC, a super PAC almost exclusively dedicated to supporting Scott has spent more than $29.5 million against Nelson.

    Democratic Sen. Claire McCaskill's vulnerable seat in Missouri has brought in more than $76 million from outside groups to the Missouri Senate race. Conservative groups led by Senate Leadership Fund, the National Republican Senatorial Committee and Americans for Prosperity, have spent more than $41 million in support of Hawley, while liberal groups have spent more than $35 million in support of McCaskill. Meanwhile, incumbent McCaskill's campaign has outspent Hawley by far, with the vulnerable Democrat spending more than $33 million and the Republican challenger spending $7 million.

    Top House races:

  • California's 39th District: $34.5 million ($21 million from candidate campaigns, $14 million from outside groups)
  • California's 48th District: $33 million ($13 million from candidate campaigns, $20 million from outside groups)
  • Washington's 8th District: $30 million ($11 million from candidate campaigns, $19 million from outside groups)

  • Pennsylvania's 1st District: $29 million ($15 million from candidate campaigns, $13.5 million from outside groups)
  • In the lower chamber, a toss-up between two minority candidates in California's 39th Congressional District, where immigrants make up a third of the population, has brought in the most money. Democrat Gil Cisneros' campaign has spent $10.5 million, while Republican Young Kim has spent just about $2 million. Kim has a strong backing of House GOP leadership though, with its super PAC Congressional Leadership PAC boasting a $6.3 million in support of Kim. House Democratic leadership is also behind Cisneros, with House Majority PAC and DCCC spending more than $5.2 million in the race.

    GOP Rep. Dana Rohrabacher's effort to defend his seat in California's 48th district has also become increasingly expensive, with candidate campaigns spending nearly $13 million and outside groups pouring in nearly $20 million. The Democratic side is eager to unseat the vulnerable Republican, with challenger Harley Rouda leading an aggressive $6 million campaign, and liberal outside groups including Independence USA PAC, House Majority PAC and DCCC spending more than $11 million to back him. Rohrabacher is backed by Congressional Leadership Fund's $4 million campaign.
