July 12, 2018 — The Survey Monkey organization polling for the Axios Media news and information website went into the field during the June 11 – July 2 period to test US Senate campaigns in 13 different states. All of the most competitive races were studied, including the 10 Trump states where a Democratic senator is standing for re-election this year.
The cumulative result actually brings some good news to both parties, but Republicans fare better because the representative predictive models suggest the GOP is in position for a net gain of at least one seat even while falling behind in their two key defense states of Arizona and Nevada.
Though the survey sampling period is long, the three-week time frame is the period consumed to survey all 13 states. Survey Monkey begins with a regular sampling universe of 3,000,000 individuals who have agreed to participate in their polls. For this project, 12,677 registered voters participated from a high of 1,280 in Arizona to a low of 457 from North Dakota. The sample size in the largest state tested, Florida, was 1,080. All of the surveys were weighted to reflect the demographic and political trend history for each state. The polling error factor for each place ranged between 4.5 and 5.5 for all states but North Dakota. In the latter, the error factor was 7.5.
There are several bright spots for both parties. Democrats fare better on the question of voter enthusiasm, which is consistent with data results recorded in virtually every poll conducted over the past year. Regarding intent to vote across the board in these Survey Monkey polls, however, both parties record about equal numbers. Overall, President Trump’s job approval scores have greatly improved. Looking at the combined 13-state universe, the president scored a 50:49 percent job approval ratio, going from a high of 60:39 percent in Tennessee to a low of 44:55 percent in Pennsylvania. But, even his lowest rating is an improvement from where he stood earlier in the election cycle.
According to the SM numbers, Democrats are in position to convert both the Arizona and Nevada races. Rep. Kyrsten Sinema (D-Phoenix) leads all three individuals competing in the Republican primary. Her strongest opponent, unsurprisingly, is US Rep. Martha McSally (R-Tucson). In the various modeling scenarios, Sinema posts leads of between one and six percentage points over Rep. McSally and far greater margins over the other two GOP candidates.
