Can Mark Dayton Give Barack Obama a Boost in Minnesota in 2012?

History suggests having a DFLer in St. Paul is unlikely to be a decisive factor, but may be worth +1.4 points to Obama in next year's presidential race

Democratic presidential candidates have had no trouble carrying the state of Minnesota in recent decades - winning nine consecutive races despite holding the governor's mansion during just three of these election cycles (1976, 1984, 1988).

Smart Politics previously debunked the myth that Democratic presidential candidates were at a disadvantage in carrying states with Republican governors at the helm in key 2012 battleground states.

That analysis of 550 statewide presidential election results dating back to 1968 found there to be no correlation between states won by Democratic and Republican presidential nominees and the partisan control of the governor's mansion. Democratic presidential candidates have won virtually an identical percentage of states in which they have held control of the governor's mansion (33.8 percent) as those in which Republicans had control (32.3 percent).

But what about in Minnesota?

A Smart Politics review of presidential elections in Minnesota since the DFL merger in 1944 finds that although Democratic presidential candidates have won a larger percentage of races and notched a larger percentage of the vote when the Gopher State governorship was under GOP control, they have performed an extra 1.4 points better than their national vote percentage when a DFLer rather than a Republican is in St. Paul.

Of course, electoral votes are all about wins and losses, and are not awarded according to expectations or beauty points.

On that score, Democratic presidential nominees - as the above study suggests - have not been deterred when Republicans hold the top statewide office in Minnesota.

Democrats have carried the Gopher State in eight out of nine presidential contests in the face of GOP governors, compared to five of seven elections with DFLers holding the governor's office. (Al Gore also won Minnesota in 2000 with a third party governor, Jesse Ventura, running the state).

The only time a Democratic presidential nominee failed to win Minnesota's electoral votes since the DFL merger with a Republican in St. Paul was in 1952, when Dwight Eisenhower defeated Adlai Stevenson in Minnesota by 11.2 points.

Democratic nominees have also secured a larger average percentage of the vote (50.4 percent to 45.4 percent) and a larger average margin of victory, or lower average margin of loss (+7.7 points to +6.3 points) with Republicans rather than DFLers in the governor's office.

However, Democratic presidential candidates have enjoyed a slightly larger bump in Minnesota against their national vote percentage with a DFLer in the governor's mansion.

Democratic candidates have performed better in Minnesota than the nation as a whole in each of the seven contests with a DFLer running the state in St. Paul: in 1956 (+4.1 points), 1960 (+0.9 points), 1964 (+2.7 points), 1972 (+8.6 points), 1976 (+4.4 points), 1984 (+9.1 points), and 1988 (+7.2 points).

Of course, Minnesota has largely voted Democratic in presidential races more than the nation as a whole during this span, so a tilt above the national average is expected in the Gopher State - and it has been +4.7 points on average under DFL gubernatorial control since 1944.

With a Republican governor in office, Democratic presidential nominees have performed better in the Gopher State than the nation as a whole in seven of nine contests (excepting 1944 and 1952) and have performed +3.3 points better than the national average overall.

In short, gubernatorial control seems to have little effect in terms of winning or losing the presidential race in Minnesota, however a home-field advantage is associated with a +1.4-point boost for Democratic nominees as compared to when it is under GOP control.

Of course, if that +1.4 points is the difference for Obama in winning or losing Minnesota in 2012, the President's reelection chances are probably very slim.

Plurality-Winning Governors Elected At Century-Long High Water Mark

The rate of gubernatorial candidates elected without the support of a majority of voters is at its highest level since the 1910s.

Political Crumbs

Seeing Red

Congressman Nick Rahall's failed bid for a 20th term in West Virginia this cycle, combined with a narrow loss by Nick Casey to Alex Mooney in Shelley Moore Capito's open seat, means that West Virginia Democrats will be shut out of the state's U.S. House delegation for the first time in over 90 years. The Republican sweep by two-term incumbent David McKinley in the 1st CD, Mooney in the 2nd, and Evan Jenkins over Rahall in the 3rd marks the first time the GOP has held all seats in the chamber from West Virginia since the Election of 1920. During the 67th Congress (1921-1923) all six seats from the state were controlled by the GOP. Since the Election of 1922, Democrats have won 76 percent of all U.S. House elections in the Mountain State - capturing 172 seats compared to 54 for the GOP.


Home Field Advantage?

When the 114th Congress convenes in a few days, Maine will be represented by one home-grown U.S. Representative: Waterville-born Republican Bruce Poliquin. With the departure of Millinocket-born Mike Michaud, who launched a failed gubernatorial bid, the Pine Tree State was poised to send a House delegation to D.C. without any Maine-born members for the first time since 1821. Three-term U.S. Rep. Chellie Pingree (born in Minnesota) coasted to reelection as expected, however Poliquin edged Kentucky-born Emily Cain by 5.3 points to keep the streak alive. Since 1876, a total of 208 of the 222 candidates elected to the nation's lower legislative chamber from the state have been born in Maine, or 94 percent.
