Results of a new poll conducted by PPP (D) were spread. The poll asked participants from Maryland for whom they will vote: Democrat candidate Hillary Clinton or Republican candidate Donald Trump.
PPP (D) poll results
Of those who responded, 61.0% said that they will vote for former First Lady Hillary Clinton, while 28.0% said that they would give their vote to businessman Donald Trump.
This poll was conducted from April 15 to April 17, among a random sample of 879 registered voters. Taking into account the poll's sampling error of +/-3.3 percentage points, the spread in voter support is statistically significant.
Putting the results in context
Single polls may include substantial biases, which is why they should be interpreted with caution. Rather than trusting the results from single polls, you should rely on combined polls or, even better, the combined PollyVote forecast that draws upon forecasts from different methods, each of which draws upon different data.
For the following analysis, we convert the candidates' raw poll numbers into shares of the two-party vote. This yields figures of 68.5% for Clinton and 31.5% for Trump.
Results vs. other polls
If we look at an average of Maryland polls, Clinton's two-party vote share is currently at 69.0%. This value is 0.5 percentage points higher than her corresponding numbers in the PPP (D) poll. This difference is within the poll's sampling error, which suggests that the poll is not an outlier.
Results compared to the combined PollyVote prediction
The latest PollyVote expects Clinton to gain 64.4% of the two-party vote in Maryland. Hence, Polly's prediction is 4.1 points below her polling numbers. Again, a look at the poll's error margin suggests that this deviation is significant.
