National contested primary average during the 2012 U.S. congressional elections
From Ballotpedia
There were 435 U.S. House seats up for election in 2012. Ballotpedia staff measured the competitiveness of the primary elections based on two factors: number of contested primaries and number of incumbents facing a primary challenge.
This page is used to provide readers with a competitiveness index similar to that used in Ballotpedia's state legislative Competitiveness Study. The results below illustrate how many primaries were contested. The first set of results represents how many of all national House of Representative primary elections were contested. The second set counts only those primaries in which one of the candidates is the incumbent member.
Summary of results
- 51.40% of incumbents who ran for re-election faced a primary challenge (202 of 393).
- 51.70% of party primaries were contested (411 of 795).
- There were six states where every primary was contested. Those six states were Hawaii, Washington,[1] Alaska, Rhode Island, Montana and Idaho.
- In four additional states, every incumbent who filed for re-election faced a primary. Arizona, New Hampshire, Nebraska and Mississippi
- The five states with the fewest percentage of contested primaries were Vermont (0%), Wyoming (0%), Wisconsin (12.50%), Colorado (21.43%) and Pennsylvania (22.22%)
- In 11 states, no incumbents faced a primary. The state with the most representatives where no incumbent faced a primary was Connecticut with five seats.

Footnotes
- ↑ Washington is one of three states with blanket primaries. Because of this, a greater percentage of primaries are classified as contested because there is only one primary for all candidates regardless of party. We classify a primary as contested if there are at least three candidates on the ballot. In other words, do voters have a choice at the polls.
