Democrats led 9 of the 10 most expensive Senate campaigns

The organization OpenSecrets published the amount of money raised and spent on the campaigns of each Senate candidate and their party. In total, Democrats raised $819,366,939 and spent $721,672,270. Meanwhile, Republicans raised 660,300,676 and spent 629,371,875.

The largest individual contributor was tycoon George Soros, who contributed 128,485,971 to Democrats. Behind the funding of many candidates are organizations such as Planned Parenthood, which started a fund to support those who advocate for federal legislation to restore abortion rights in the wake of the Supreme Court's recent ruling.

Most expensive Senate races

Democrats will keep their majority in the House after the midterms. Tight victories by Democratic candidates in Nevada and Arizona bring the party to a total of 50 seats. This, coupled with the tie-breaking vote of Vice President Kamala Harris, allows them to continue to control this legislative body.
