Gallup announced last week that they are discontinuing their daily presidential approval tracking poll, opting instead to provide topline numbers weekly on Monday and detailed demographics monthly.

Since 2008, the well-known firm had been tracking presidential approval as a question in their privately sponsored Gallup-Sharecare Well-Being Index. Rather than conducting landline- or cell phone-based interviews, more of those responses are instead being gathered by mailer.

“We are making this change largely because the source for these daily data, the Gallup Daily tracking program — made possible by a client-supported commitment to daily interviewing on a wide variety of well-being metrics — is shifting from telephone surveys to reporting mail surveys on a monthly basis,” Gallup editor-in-chief Frank Newport said in the announcement.

The decision leaves Rasmussen Reports as the only remaining pollster to provide journalists, political junkies and news consumers daily data.

Naturally, it isn't going over well with mediates who oppose President Trump. Politico, the "liberal-leaning" D.C.-based website, wrote in their story covering Gallup's announcement:

Gallup’s announcement leaves the Republican-leaning pollster Rasmussen Reports as the only remaining public source of daily presidential approval updates. Trump last week touted his 46-percent approval rating in the Rasmussen poll — even though a 53 percent majority still disapproved of his job performance. The latest Rasmussen results on Wednesday were slightly worse for the president, with his approval rating slipping to 44 percent.

If Rasmussen Reports is a "Republican-leaning pollster," then what exactly does that make everyone else? While it's true that they consistently find more favorable approval ratings for the president than other polls, including Gallup, it's also true that they have established a more accurate track record of gauging his true level of support among the electorate.

Gallup tracks adults, not the voting electorate.

Let's take a look at the top 10 pollsters aggregated by Real Clear Politics (RCP) in 2016 regarding the national popular vote, using a measure of accuracy proposed by Martin, Traugott and Kennedy and used by the American Association for Public Opinion Research to rank accuracy.

Pollster Clinton Trump Odds Ratio Accuracy Rasmussen Reports 45% 43% 1.00 0.00 UPI/CVOTER 49% 46% 1.02 0.02 CBS/New York Times 45% 42% 1.02 0.02 Politico/Morning Consult 45% 42% 1.02 0.02 McClatchy/Marist 44% 43% 0.98 -0.02 Bloomberg/Selzer 44% 41% 1.03 0.03 Reuters/Ipsos 42% 39% 1.03 0.03 Fox News 48% 44% 1.04 0.04 Boston Herald/Franklin Pierce/RKM 48% 44% 1.04 0.04

Why aren't those who performed more poorly than Rasmussen referred to as "Democrat-leaning pollsters"? How about "less accurate-leaning pollsters"?

After its monumental failure in 2016, we had high hopes the polling industry would finally engage in a long overdue exercise in introspection. The 2016 presidential election wasn’t the first major polling blunder in U.S. politics, but it does appear to be the one in which media pollsters lost the public trust.

A meager 26% say they trust most political polls, while 55% do not.

Rather than show a little humility for the greater good of the industry, "Democrat-leaning" pollsters had a conversation among themselves, excluding those of us who polled the election correctly. The same pundits and glorified poll-readers (forecasters) who trashed Gallup during and after the 2012 presidential election now turn to them to validate their own biases and preconceived notions.

Gallup has been polling since before I was in diapers, and I get no pleasure from criticizing them. Over the course of decades, they were wrong only one time before they underestimated Barack Obama's support in 2012. In 1948, Gallup had incumbent Democratic President Harry S. Truman trailing Republican Thomas E. Dewey by final survey, 49.5% to 44.5%.

That's undeniably a solid track record. But the fact remains Gallup's political polling has been unverifiable since they quit the horserace business after their misfire in 2012. If you don't have confidence enough in your own data to test it against actual Election Day results, I'm not sure how much you can or should contribute to the conversation.

Trump easily defeated Hillary Clinton in the Electoral College by carrying states Republicans haven’t carried since the 1980s. The PPD Big Data Poll, which was not aggregated and considered to use an experimental online methodology, ended up one of only two state-level surveys that predicted his victory, the other being Trafalger Group.

In several states including Wisconsin, Michigan and Pennsylvania, Trump trailed outside the average margin of error in "Gold Standard" polls.

It's not only "Republican-leaning pollsters” arguing that results matter.

Mark Penn, the co-director of the Harvard-Harris Poll and former pollster for Bill Clinton during six years of his presidency, has repeatedly mirrored my criticisms of the industry. His poll eliminates undecided voters, tracks likely voters and consistently pegs Trump's approval around 45%, very similar to Rasmussen.

Mr. Penn warned that "reality versus research will again be tested, and reality always wins."
