Comparing campaign finance data in state elections, 2018-2020

*This report first appeared on Ballotpedia as a part of our ongoing partnership. We are proud to provide campaign finance data to Ballotpedia for state-level elections. Learn more about our partnership here.*

The value of money in state-level politics extends beyond purchasing power. Campaign cash allows candidates to promote their message and turn out their voters, but perhaps more importantly, it often represents momentum. While having the biggest campaign account is no guarantee of success at the polls, studies conducted by the Center for Responsive Politics and the Campaign Finance Institute found a strong correlation.

As part of our partnership with Ballotpedia, we took a closer look at how the two major political party candidates for state legislatures in nine states—Arizona, Florida, Michigan, Minnesota, North Carolina, Ohio, Pennsylvania, Texas, and Wisconsin—performed with fundraising in a cycle-vs-cycle comparison from 2018 to 2020.

Highlights from each state appear below. Click on the link under each state to see the full reports.

Arizona

Here’s what we found in Arizona:

  • The overall contributions favor the Republicans, both in the aggregate and per candidate. As of the semiannual reports, Republican candidates for the Arizona State Legislature had raised $5.4 million, while Democrats had raised $4.2 million. Similarly, Republican candidates had raised on average $51,490, while Democrats had raised on average $48,450.
  • The percentage of change between 2018 and 2020 also favors the Republicans in several key metrics. The total number of individual donations to Republican candidates is up 27.3 percent compared to a 6.3 percent increase to Democrats. It’s also worth noting that while Democrats have significantly more small-dollar donations than Republicans, the momentum here is with the Republicans. The GOP saw a 38.6 percent increase in the number of donations for $100 or less, while Democrats stayed relatively flat with a 0.5 percent increase in small-dollar donations.

Similarly, Republicans candidates had raised on average $108,513.51, while Democrats had raised on average $37,424.07.

The number of individual donations to Democrats is up 64 percent, while the number of donations to Republican candidates is up 79 percent. The number of small-dollar donations (less than or equal to $100) to Democrats declined 14 percentage points compared to 2018, while it held steady for Republicans.

Limitations

The direct comparison between fundraising data from 2018 and 2020 is limited by at least two factors. First, the same seats and offices were not necessarily up for election in both years. For example, Michigan held elections for both chambers (the state Senate and House of Representatives) in 2018, but only for the House in 2020. Second, additional offices on the ballot in a year might affect the amount of money raised in state legislative elections. For example, among the states studied, Florida, Minnesota, Michigan, Ohio, Pennsylvania, Texas, and Wisconsin all held gubernatorial elections alongside their state legislative elections in 2018 but not 2020.
