Which House incumbents are most likely to lose?
- Massscorecard.org analyzed the House incumbents to determine the most vulnerable in the 2012 election.
- The list of the most vulnerable incumbents appears below; we will report on our accuracy after the elections.
- Most vulnerable Democrats
- Most vulnerable Republicans
- Retiring (perhaps due to vulnerability)
- Lost Primary (perhaps due to vulnerability)
- Changed District (perhaps due to vulnerability)
- Our methods:
- We looked for incumbents whose party is a mismatch with the people in that district.
- For incumbent Democrats, if McCain won the district in 2008, the incumbent is vulnerable.
- For incumbent Republicans, if Obama won the district in 2008, the incumbent is vulnerable.
- The degree of vulnerability is scored by the percentage difference between Obama and McCain.
- We also compared the results of the 2004 election, and added in the the percentage difference between Kerry and Bush.
- The overall score indicates the degree of incumbent vulnerability; we list the incumbents sequenced by this vulnerability score.
- A higher score (larger negative number) indicates a higher vulnerability.
- Our limitations:
- The 2012 election includes redistricting from the 2010 census; that often mixes up districts and also mixes up this analysis.
- We note which districts are shifted due to redistricting; those districts are harder to predict because they have never voted before within those district lines.
- Incumbents work hard to ensure that redistricting HELPS them rather than HURTS them; but the results depend on the majority party of their state legislature.
- The prevalence of vulnerable Republicans (26) over vulnerable Democrats (6) is due to Obama's large victory in 2008; districts are more likely to look Democrat than to look Republican.
- Accordingly, we omit incumbents whose district vote in the 2004 presidential race more than compensated for the 2008 presidential race.
- You can download the list of incumbents who fell off the vulnerability list during that process.
- We also note if the incumbent is a freshman (first elected in 2010) which makes them even more vulnerable (but not indicated in the score).
- This method has been used by myself and my political cronies to predict vulnerable Massachusetts House races in the past.
- This is the first application to federal House races; come back after November to see how it works!
