Are Minnesota's U.S. House Seats Safer for Incumbents Today Than in the Past?

Bookmark and Share

This report is Part 3 in a series on the incumbency advantage in Minnesota politics.

The first two parts of Smart Politics' examination into the historical incumbency advantage in Minnesota politics delved into the extent to which more seasoned members of Congress have a greater likelihood of winning reelection as well as a case study of how electoral history is on the side of Congresswoman Michele Bachmann to win a third term in 2010.

Overall, U.S. Representatives from the Gopher State on the general election ballot have an 87 percent reelection rate over the past 150 years. The conventional wisdom is that, nationwide, U.S. House incumbents in today's political environment are safer than ever - with increasingly partisan-drawn district lines and the large campaign warchests Representatives are able to build while in office.

But a Smart Politics analysis of Minnesota's electoral history tells a different story. Aside from a decade and a half span during the rise and fall of the state's three-party system in the 1930s and 1940s, Minnesota's incumbents are being reelected at the same rate as they were 100 years ago.

Smart Politics studied each of the Gopher State's 568 general and special election matchups since statehood, and grouped these election results into decade-long census periods. The winning percentage of U.S. House incumbents was then calculated for each census period.

One of the most striking findings is not that incumbents are being reelected at a high rate, but that this rate is no higher today than it was in the 1970s, 1920s, or even the first decade of the 1900s.

In the current census period, 2002-2008, Minnesota's U.S. House incumbents have been reelected at a rate of 93.1 percent, or 27 of 29 contests (with 6-term GOPer Gil Gutknecht losing in 2006 and DFLer Bill Luther losing his seat after redistricting in 2002).

In the previous census period, 1992-2000, 94.4 percent of incumbents were reelected to D.C., or 34 out of 36 (with DFLers Gerry Sikorski and David Minge losing in 1992 and 2000 respectively).

While these recent incumbency reelection rates are extraordinarily high, they are no higher than they have been throughout most of the 20th Century in the Gopher State:

· From 1902-1910, Minnesota Representatives were reelected at a 94.3 percent rate.
· From 1912-1920, incumbents won reelection at a 92.9 percent rate.
· From 1922-1930, Representatives won their reelection bids at a 90.9 percent clip.
· From 1952-1960, U.S. House members were reelected at a 93.0 percent rate.
· From 1962-1970, incumbents won reelection at a 92.1 percent rate.
· From 1972-1980, Gopher State representatives were reelected at a 100 percent rate.
· From 1982-1990, incumbents won 92.3 percent of their general election contests.

Note: The second column from the right indicates Representatives who attempted but did not get on the general election ballot because they failed to receive their party's nomination.The far right column combines all other U.S. Representatives who did not run for reelection for a variety of reasons: retirement, resignation, running for another office, or death. In addition to the 558 U.S. House seats listed above, an additional 10 seats have been on the ballot in which there was no previous incumbent (i.e. newly created seats after reapportionment in 1857, 1872, 1882, 1892, 1902, and 1912). Data compiled by Smart Politics.

The most volatile period in Minnesota electoral history was in the 1880s, when incumbents were barely reelected a majority of the time, at just 52.9 percent. This period also coincides, not coincidentally, with the most competitive period of U.S. House elections in state history, with 56 percent of U.S. House races during this census period decided by less than 10 points (the rate from 2002-2008 is just 15.6 percent).

The only periods in which incumbents were reelected at a notably lower rate in the 20th Century were 1932-1940 (61.5 percent) and 1942-1950 (83.3 percent). This era coincided with the rise and fall of the 3-party system in the Gopher State: Republicans, Democrats, and Farmer-Laborites (the DFL merger occurred in 1944).

In fact, 22 of the 62 unseated U.S. House incumbents in Minnesota history lost their general election bids in a 16-year period, from 1932-1948. The three-party system turned over U.S. Representatives at a 3.2 times higher rate (30.5 percent) than the 75 years before (1857-1930) and the 60 years thereafter (1950-2008) (9.6 percent).

Data compiled by Smart Politics.

During the three-party era, Farmer-Laborites pried away several Republican seats, particularly in 1932, when the Gopher State's nine U.S. House seats were all elected in a statewide, at-large election. The Minnesota GOP U.S. House delegation was reduced from 9 members after the 1930 election to 3 after 1932. Democrats were able to hold onto only one seat, the 2nd CD, during the 1930s (district elections were resumed in 1934).

Republicans, however, won many of these seats back in 1938, when four Farmer-Laborite incumbents were defeated. After the DFL merger in 1944, six Republican incumbents lost their seats in the next three elections, including 8-term Republican Melvin Maas, 7-term GOPer William A. Pittenger, and Harold Knutson, who served in the U.S. House for 16 terms.

Pittenger, in fact, has the notoriety of losing his 8th CD seat two times: first, as a 3-term incumbent in 1936 to Farmer-Laborite John Bernard, and then again in 1946 as a 7-term incumbent to DFLer John Blatnik (Jim Oberstar's predecessor).

Mary Burke: English First?

While multiculturalism and bilingualism are increasingly en vogue in some quarters as the world seemingly becomes a smaller place, one very high profile 2014 Democratic candidate does not shy away from the fact that she only speaks one language: English. In an attempt to highlight her private sector credentials working for Trek Bicycle, Wisconsin Democratic gubernatorial nominee Mary Burke boasts on her campaign bio page how she made great strides in international business dealings...while only speaking English: "Despite not speaking a single foreign language, she established sales and distribution operations in seven countries over just three years." Note: According to 2010 Census data, nearly half a million Wisconsinites over five years old speak a language other than English at home, or 8.7 percent, while 4.6 percent of Badger State residents do not speak English at all.


Does My Key Still Work?

Much has been made about Charlie Crist's political transformation from Republican to independent to Democrat en route to winning the Florida GOP and Democratic gubernatorial nominations over a span of eight years. Party-switching aside, Crist is also vying to become just the second Florida governor to serve two interrupted terms. Democrat William Bloxham was the first - serving four year terms from 1881 to 1885 and then 1897 to 1901. Florida did not permit governors serving consecutive terms for most of its 123 years prior to changes made in its 1968 constitution. Since then four have done so: Democrats Reubin Askew, Bob Graham, and Lawton Chiles and Republican Jeb Bush.
