Tight Senate Races Developing in Arizona and Florida

The gubernatorial contests in Ohio and Wisconsin are also very close in the final days of campaigning. 

Vancouver, BC [November 5, 2018] – Residents of two American states are headed to this year’s mid-term election with closely contested U.S. Senate races, according to a series of new polls conducted by Research Co. in five American states.

The surveys also show remarkably tight contests in three gubernatorial elections.


In the race to take over the U.S. Senate seat vacated by Jeff Flake in Arizona, Democrat Kyrsten Sinema and Republican Martha McSally are locked in an extremely close race (50% to 49% among decided voters)

Incumbent Republican Doug Ducey seems headed for re-election as the Governor of the Grand Canyon State, with a 14-point lead over Democratic rival David Garcia (57% to 41% among decided voters).


Democrat Bill Nelson’s quest for a fourth-term in the United States Senate could see the closest race of his career. Nelson holds a two-point edge over Republican Rick Scott (51% to 49%).

In the Sunshine State’s gubernatorial race, Democrat Andrew Gillum is also ahead of Republican Ron DeSantis by two points (50% to 48%).

New Mexico

Incumbent Democratic U.S. Senator Martin Heinrich is first in New Mexico (52% among decided voters), followed by Republican Mick Rich (36%) and Libertarian Gary Johnson (12%).

In the contest to replace New Mexico Governor Susana Martinez, Democratic candidate Michelle Lujan Grisham holds a 12-point advantage over Republican challenger Steve Pearce (56% to 44% among decided voters).


Incumbent Democratic U.S. Senator Sherrod Brown has a sizeable lead over Republican challenger Jim Renacci in the Buckeye State (58% to 42% among decided voters).

The race for governor is extremely tight, with both Democrat Richard Cordray and Republican Mike DeWine supported by 49% of decided voters in Ohio.


Incumbent U.S. Senator Tammy Baldwin appears headed to a new term in office, with a 12-point advantage over Republican rival Leah Vukmir in the Badger State (56% to 44% among decided voters).

The election for Governor is very close, with Democratic challenger Tony Evers barely ahead of incumbent Republican Scott Walker (49% to 48% among decided voters).


Results are based on online studies conducted from November 1 to November 3, 2018, among representative samples of 450 voters in five American states: Arizona, Florida, New Mexico, Ohio and Wisconsin. 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.
