Indiana Statewide Survey Polling Analysis
On behalf of IndyPolitics.org, Mason Strategies conducted a survey of 600 likely voters in Indiana using
live interviewers, from October 15 to 20, 2018. The topline results and methodology statement are
included below. This memo covers federal races; results on state and Indianapolis-specific results will be
released in coming days.
U.S. Senate Race:
Mike Braun leads Sen. Joe Donnelly 47% to 43%, with 3% for Libertarian Lucy Brenton and 7%
undecided, in a poll conducted three weeks before Election Day.
This result is statistically tied, due to the 3.9% margin of error applying to each data point. That is,
Braun’s vote share in this poll is between 43% and 51%, while Donnelly’s vote share is between 39% and
47%. For this reason, Braun’s lead is not considered statistically significant. There are also 7% undecided,
and another point or two could come from the third-party candidate (whom we tested by name on the
ballot) This presents a level of uncertainty that needs to be factored into the analysis.
Braun is likely favored, but Donnelly could still win. This poll, like every other poll, is not a prediction of
the vote on November 6th
, nor is it meant to be. Part of the reason there is skepticism over polling is due
to observers ascribing more certainty to the outcome of races than the data itself shows.
There is no difference in voter enthusiasm. 72% of Braun voters say they are “extremely” or “very”
enthusiastic to vote, compared to 74% of Donnelly voters. 42% of Braun voters say their enthusiasm is
“extreme”, to 41% of Donnelly voters.
There is a 29 point gender gap, as men prefer Braun 55% - 36%, while women prefer Donnelly 39% to
49%.Independents favor Donnelly 48% - 37%. Donnelly also has higher support among Democrats (90%)
than Braun does among Republicans (85%). That is not enough to overcome the state’s partisan lean.
Exploring the “Kavanaugh Effect”:
35% say that Donnelly’s opposition made them less likely to support him, compared to 30% that said
more likely, and 32% who said it had no impact.There is a 25-point gender gap here, but education also
plays a role here. College-educated women say “more likely” by a 43% to 31% margin, while non-
college-educated women are split at 30%-29%.
Looking at intensity (which is the best predictor of action), 29% of voters said Donnelly’s no vote made
them “much less likely” to support him; 25% said “much more likely”. Here, 72% of those who said
“much less likely” are self-identified Republicans; while 66% of those who said “much more likely” are

self-identified Democrats. That is to say, most people responding to this question were already likely to
be voting for their preferred candidate.
It is difficult to separate from the rest of the political activity surrounding a closely contested election.
However, there is some evidence of a “Kavanaugh effect”. Specifically, party self-identify seems to
supersede ideology self-identity. By a 40% to 16% margin, moderate to liberal Republicans say
Donnelly’s opposition made them less likely to support him; meanwhile, by a 45% to 7% margin,
conservative and moderate Democrats said it made him more likely.
This suggests that the Kavanaugh vote unified the Republican Party. Given the potentialfor weakness
among moderate and Trump-skeptical Republicans, this is a positive electoral force for Republicans.
On the flip side, those 83% of those who said “much more likely” to support Donnelly for voting against
Kavanaugh are “extremely or very” enthusiastic to vote, compared to 75% who said “much less likely”.In
the end, the likely impact of the Kavanaugh vote seems to have been to solidify Braun’s voter base while
boosting turnout among the Democratic voting base. It is unclear how much this would have happened
anyways, even without the Kavanaugh hearings.
Generic Ballot:
The Congressional generic ballot mirrors the Senate race, at 48% to 43% for Republicans. This suggests
that Donnelly is not getting the crossover support he needs to win in a red state. Unlike the Senate race,
there is an enthusiasm gap on the generic ballot in the Democrat’s favor. Only 66% of Republican voters
say they are “extremely” or “very” enthusiastic, compared to 77% of Democratic voters. This is unlikely
to swing the tide in any of Indiana’s Congressional races, however, which are largely viewed as non-
competitive.
There is a 25-pt gender gap on the generic ballot: men are voting Republican 55% to 37%, while women
are voting Democratic 42% to 49%.
Trump Approval:
Trump’s job approval rating in Indiana is 52% to 46%, which is about 5 points fewer than the 57% of the
vote he won in 2016. Despite the 6-point net approval, net strong approval is -2%, as 41% “strongly
disapprove” to 39% who “strongly approve”. Like with the above, we see a strong gender gap here.

Methodology Statement
On behalf of IndyPolitics.org, Mason Strategies, LLC, a research firm located out of Woodbridge, Virginia, conducted a telephone
survey of 601 likely voters in Indiana. The survey was completed from October 15 - 20, 2018 using live interviewers from a call
center who called of landline and cell phones. The survey used RBS (Registration-Based Sampling) methodology, using voter
registration records to create a random sample of voters who have voted in at least one of the previous four general elections in
Indiana, or were newly registered to vote in Indiana. The final sample was weighted for region, age, and education.
The survey has a margin of error of +/- 3.9% at the 95% confidence level. The margin of error applies to each individual data
point at the topline level. When applying margins of error to relative analysis (e.g., a ballot test), it would apply to each data
point and not the margin between the two. Thus, even a difference greater than 3.9% between two data points may not be
statistically significant. Sampling error is larger for subgroup analysis.
The survey was designed to minimize error through question wording and sequence; however, every question asked introduces
some element of bias in the questions that follow.
