Post-New Hampshire Primary Polling Suggests Trump's Historically Well Positioned To Capture GOP Nomination

To the chagrin of the sixty-to-seventy-odd percent of Republicans who do not support Donald Trump as their nominee for president, the billionaire firebrand is looking mighty dominant in post-New Hampshire primary polling. But how is he standing up compared to past polling front-runners at this point in the campaign? For Trump critics, the news is pretty bleak, yet not without at least a faint glint of hope.

In my experience, it's always best to start with the bad news, so here goes:  in nearly every presidential primary since 1976, the national polling leader between the New Hampshire and South Carolina primaries has gone on to become their party's nominee. Specifically, of the fifteen post-New Hampshire national primary polling leaders examined over the last forty years, twelve eventually earned their party's nomination (or 80% of the time).

Having said that, Donald Trump is currently the Republican's national polling leader, and by a wide margin. With one day remaining until South Carolinians head to the polls, Trump's averaging 36% support from Republicans across seven primary surveys conducted after the New Hampshire primary, reaching as high as 41% and as low as 26%. He maintains an average seventeen point advantage over his next closest competitor, Ted Cruz.

Faced with the numbers, and what we know of history, what else is there to conclude other than the fact that Trump appears headed for the Republican nomination?

Unlike Romney 3.0, Ex-Nominees Do Not Historically Poll Very Well In National Primary Surveys

Former Presidential candidate Mitt Romney has stormed back onto the political scene in a big way this month, reaching out to former mega-donors, reassembling the 'old team,' and meeting with fellow potential major candidates. And as poll after poll has shown, rank-and-file Republican Party members across the nation have taken notice.

A surprisingly solid 59% of Republicans say they'd like for the former nominee, who attracted just over 47% of the popular vote in his failed 2012 bid, to give it another go in 2016. Only 26% think he should sit it out. Romney consistently sports the highest favorability ratings of the potentially large field of Republicans candidates, at least where it counts - among the base. Last but not least, he leads comfortably in every national horserace survey of the GOP primary taken to date.

That final fact is somewhat unique in a historical context, and especially so when looking back over the last thirty years. Ex-presidential nominees frequently pop-up in the following cycle's primary polling. But it's much less frequent that they cast such a dominating presence over the rest of the field, so consistently.

In fact, looking back at ALL twenty-one ex-nominee's polling performance in the following cycle's presidential primary in the modern polling era, former presidential nominees can be said to fall into three tiers.

1. Tier 1 - this group of former nominees had no trouble recapturing the party faithful's hearts and minds for the second time in a row following their presidential loss. Qualification for membership in this group requires the ex-nominee poll in first place in at least half of the following presidential primary surveys taken that include that candidates name. For example, because Mitt Romney has appeared in eight national 2016 GOP primary surveys to date, and has led in each, he would qualify for membership in this group. Other ex-nominees falling into this group are Al Gore in 2004, Richard Nixon in 1964, Adlai Stevenson in 1956, and Thomas Dewey in 1948.
2. Tier 2 - this group of former nominees polled reasonably well in primary surveys taken after their presidential loss, almost always hitting double digits, even finding themselves at the summit of some random surveys. They fall short, however, of the polling status achieved by the failed nominees in the above group. Seven of the twenty-one ex-presidential nominees from 1936 to 2012 fall into this category.
3. Tier 3 - ex-nominees in this group are defined either by their surprisingly shoddy, if not embarrassing polling performance in the following cycle's primary survey, or by their unwillingness to even entertain the idea of the presidency ever again, evidenced by their total exclusion from the following primary's polling. Nine of the twenty-one ex-presidential nominees from 1936 to 2012 fall into this category. 

The Predictive Power of (Very) Early Presidential Primary Polling Part IV - 2008 GOP & 1980 Democratic Primaries

Hillary Clinton and Chris Christie would stand a fair chance of winning their party's nomination if Republicans and Democrats decided on a nationwide basis at the ballot box today. But then again, so would General Colin Powell at a similar point in 1997, and Senator Edward Kennedy in 1981. Unfortunately for them, that's not how the party's pick their nominees.

As discussed in part 1 of this series, there have only been three instances in the last forty years of presidential primary polling in which the frontrunner in the first year following the preceding election went on to win his party's nomination.

Clinton and Christie can't like those odds. But about 80% of the time, or three out of the last fifteen primaries, early surveys were unreflective of final results.

The twelve Republican or Democratic primaries since 1976 to feature non-predictive early primary polling split roughly into two groups - 1) those where the eventual nominee showed up in early surveys, but not as the frontrunner (as discussed in Part 2 and 3 of this series), and 2) those where the eventual nominee seems to have come from nowhere, emerging in much later polling, sometimes after primary contests have begun.

This fourth installment will continue to focus on group one above...namely the 2008 Republican and 1980 Democratic Presidential Primaries.


2008 - THREE YEAR FRONTRUNNER FINISHES WITH ZILCH

It's been less than ten years, but some may be surprised to recall that there was a definite polling frontrunner in the early 2008 primary process - it just wasn't John McCain. Former New York City Mayor Rudy Giuliani had been in the spotlight since the September 11th terrorist attacks, which took place in the waning three months of his eight year mayorship. That adoration turned to presidential speculation not long after the Republicans renominated President Bush in 2004. By the next year, the speculation had translated into a fairly consistent lead in early 2008 Republican presidential primary polling:

Across sixteen surveys in the first year following the 2004 presidential election, Giuliani led likely GOP foes in twelve of them, tied for first place in two, and finished a close second place in the remaining two.
