Campaign Spending: At-large vs. Single-member District Electoral Systems
Serendipitously, I recently came across a capstone report
by Jason Malinowski entitled “Campaign Spending in City Council Elections: A
Comparison of At-Large and District Contests.” In it, Malinowski examines the relationship
between campaign spending in City Council elections and the type of electoral
system—at-large, mixed, or single-member district—employed by the city. One of
the arguments for single-member district electoral systems is that candidates
do not have to raise and spend as much money as they do in a city with an
at-large electoral system. This increases the opportunities for candidates to run
for city council seats. But is it true that winning a city council seat in a
single-member district electoral system is less expensive than competing for a
city council seat in an at-large electoral system?
Malinowski notes that there are few studies comparing
campaign spending and type of electoral system. He provides the table below
comparing three empirical studies:
Malinowski compares the mean spending by winning candidates
in 19 large cities that employ different methods of electing council candidates.
The graphic displays his results:
In Austin, according to Malinowski’s data, a winning
candidate spent a mean of $161,000 in the at-large system. In 2014, the mean
spending by a winning candidate was $119,153. The difference is $41,847, a 26
percent decrease in mean campaign spending. The difference is less than what
Malinowski found, but the effect is noteworthy. In his conclusion, Malinowski states:
. . . [T]his study finds a strong relationship between city
council electoral system and the amount of campaign funds spent by winning
candidates. Specifically, it finds that candidates for at-large contests expend
a significantly greater amount of funds than district candidates. This
observation appears consistently across a set of description statistics comparisons
and regression analyses. The difference in spending is estimated to be approximately
$76,000. These findings suggest that cities with at-large systems, who want to increase
political participation and decrease the influence of moneyed special interests,
may wish to evaluate a change to a district or mixed electoral system.
