Report: Public Opinion Polls Probably Underestimate Donald Trump's Popular Support

I argued that the polls were underestimating Trump's strength back in the summer months, particularly with reference to the left's monstrous sanctuary city policies. And now here comes statistical evidence that polls are likely shorting the Manhattan real estate developer's support.

At the Los Angeles Times, "Polls may actually underestimate Trump's support, study finds":

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.

Among the complicating factors is this: The gap between online and telephone surveys has narrowed significantly in surveys taken in the last few weeks. That could suggest that Republicans who were reluctant to admit to backing Trump in the past have become more willing to do so recently.

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.

Some of the polls that show heavy support for Trump have also shown him doing better among self-identified independents who lean Republican than among regular GOP voters. At least some of those independents may not be in the habit of voting in primaries and caucuses, which could make a robust turnout operation even more necessary.

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...

And that was something I also suggested, in my post the other day, "Donald Trump Campaign Lags in Mobilizing Iowa Caucus Voters." With Trump's celebrity, is old-time voter mobilization passé?

We won't know until February.
