Democrats Heavily Favoured in Six U.S. Senate Races

Incumbents lead in California, Michigan, Minnesota, New York and Pennsylvania.

Vancouver, BC [November 4, 2018] – Several members of the United States Senate appear ready to return to Washington D.C. after this year’s mid-term election, according to a series of new polls conducted by Research Co. in five American states.

The surveys also show Democratic Party candidates edging out Republican challengers in five gubernatorial races.


As was the case in 2016, the race for the U.S. Senate in the Golden State features two Democratic contenders. Incumbent Dianne Feinstein (62%) is ahead of challenger Kevin de León (38%).

Democratic gubernatorial candidate Gavin Newsom holds a 20-point lead over Republican rival John Cox among decided voters in California (60% to 40%).


Incumbent Democratic U.S. Senator Debbie Stabenow appears headed for a third term in office, with a 17-point lead over Republican John James (58% to 41%) in the Great Lakes State.

In the contest to replace Michigan Governor Rick Snyder, Democratic candidate Gretchen Whitmer is ahead of Republican Bill Schuette (52% to 47% among decided voters).


Incumbent U.S. Senator Amy Klobuchar of the Democratic Party holds a comfortable lead over Republican Jim Newberger in the North Star State (60% to 38%).

In the special election to fill the U.S. Senate seat vacated after the resignation of Al Franken, Democrat Tina Smith is ahead of Republican Karin Housley (55% to 43%).

Democratic candidate Tim Walz is in a good position to replace fellow party member Mark Dayton as Governor of Minnesota. Walz holds a seven-point lead over Republican Jeff Johnson (53% to 46%).

New York

Democrat Kirsten Gillibrand would earn a new term in the U.S. Senate representing the Empire State, with a sizeable advantage over Republican Chele Chiavacci Farley (66% to 34%).

Incumbent Governor Andrew Cuomo of the Democratic Party holds a 19-point lead over Republican contender Marc Molinaro (58% to 39%) in New York.


Democrat Bob Casey Jr. would win a third consecutive election to the U.S. Senate in the Keystone State. Casey holds a 17-point lead over Republican rival Lou Barletta (58% to 41%).

Incumbent Democratic Governor Tom Wolf is 15 points ahead of Republican challenger Scott Wagner (57% to 42%) in Pennsylvania.


Results are based on online studies conducted from November 1 to November 3, 2018, among representative samples of 450 voters in five American states: California, Michigan, Minnesota, New York and Pennsylvania. The data has been statistically weighted according to U.S. census figures for age and gender in each state. The margin of error—which measures sample variability—is +/- 4.6 percentage points for each state.
