PPP (D) published the results of a new poll. In this poll, participants from Maryland were asked for whom they will vote: Hillary Clinton or Donald Trump.
PPP (D) poll results
Of those who answered the question, 61.0% said that they plan to vote for former New York Senator Hillary Clinton, whereas 28.0% declared that they would give their vote to businessman Donald Trump.
The poll was conducted from April 15 to April 17 with 879 registered voters. The margin of error is +/-3.3 points. This means that the poll results for both parties' candidates differ significantly.
Putting the results in context
In general, however, you should not have too much faith in the results of single polls, since they may incorporate large errors. Rather than relying on results from single polls, we recommend to consult combined polls or, even better, the combined PollyVote forecast that uses different methods and data.
For the following analysis, we translate Clinton's and Trump's raw poll numbers into shares of the two-party vote. This yields figures of 68.5% for Clinton and 31.5% for Trump.
Results in comparison to other polls
If we look at an average of Maryland polls, Clinton's current two-party vote share is at 69.0%. In comparison to her numbers in the PPP (D) poll Clinton's poll average is 0.5 percentage points better. This margin is within the poll's sampling error, which means that the poll is not an outlier.
Comparison to the combined PollyVote
The latest PollyVote forecasts Clinton to gain 64.4% of the two-party vote in Maryland. That is, the combined PollyVote is 4.1 points below her polling numbers. Again, a look at the poll's error margin reveals that this deviation is significant.
