Donald Trump leads the GOP presidential field in polls of Republican voters nationally and in most early-voting states, but some surveys may actually be understating his support, a new study suggests.

The analysis, by Morning Consult, a polling and market research company, looked at an odd occurrence that has cropped up repeatedly this year: Trump generally has done better in online polls than in surveys done by phone.

The firm conducted an experiment aimed at understanding why that happens and which polls are more accurate — online surveys that have tended to show Trump with support of nearly four-in-10 GOP voters or the telephone surveys that have typically shown him with the backing of one-third or fewer.

Their results suggest that the higher figure probably provides the more accurate measure. Some significant number of Trump supporters, especially those with college educations, are “less likely to say that they support him when they’re talking to a live human” than when they are in the “anonymous environment” of an online survey, said the firm’s polling director, Kyle Dropp.

With Trump dominating political debates in both parties, gauging his level of support has become a crucial puzzle. The Morning Consult study provides one piece of the solution, although many other uncertainties remain.

Another issue is that not only can polls change over time, but Trump’s support in pre-election surveys might not fully translate into actual votes. He has not invested as heavily as some of his GOP rivals in building the kind of get-out-the-vote operation that candidates typically rely on, particularly in early voting states.

On the other hand, a candidate of Trump’s level of celebrity may simply not need much of a get-out-the-vote operation. No one really knows.

Another complication is that most polls made public this year have been of people nationwide, not of voters in the states that actually hold the first primaries. In Iowa, which will kick off the election season with party caucuses on Feb. 1, Trump has slipped into second place, trailing Sen. Ted Cruz of Texas in the majority of recent polls…
