Putting the results in context
In general, however, a good strategy is to not have too much faith in the results of single polls, because they can incorporate large errors. Rather, one should check how a poll's results compare to benchmark forecasts.
In order to make the results comparable to forecasts from other methods, you can convert them into shares of the two-party vote. This procedure yields values of 47.9% for Clinton and 0.0% for Trump. For comparison: 48.9% was obtained by Clinton in the PPP (D)PPP (D) poll on March 23, for Trump this result was 51.1%. The most recent PollyVote predicts Clinton to gain 46.8% and Trump % of the two-party vote in Pennsylvania.
