Midterms, History and the Expectations Game for the House in 2010

One of the jobs of nonpartisan analysts is to keep the parties honest. Partisans have a tendency to talk themselves into certain opinions, and there are enough data out there to make any case they wish. Nowhere is this more obvious than in the expectations game.

[IMGCAP(1)]Over the past few months, both Democratic and Republican officeholders have noted that midterm elections usually result in losses — often sizable losses — for the president’s party. Democrats make the assertion so that they’ll be able to claim victory if the party suffers a small net loss next November, while Republicans cite the trend as a recruiting tool and to boost party morale.

Just recently, a Republican Congressional candidate told me that he expected his party to make big gains next year “because the average midterm loss for a president’s party is 30 seats.— That number has also been cited by Democratic Congressional Campaign Committee Chairman Chris Van Hollen (Md.) in his effort to set a bar that he certainly can beat.

In fact, “averaging— midterm results over the past 100 or 150 years, or even the past 50 years, to set expectations for 2010 makes no sense. Averages are meaningless when you have a wide range of outcomes, as there have been in midterm elections since 1960, a reasonable place to start examining recent midterm trends.

Over the past five decades, there have been 12 midterm elections. Five of them resulted in large losses of at least 20 seats by the president’s party: 2006 (30 seats), 1994 (52 seats), 1982 (26 seats), 1974 (49 seats) and 1966 (47 seats).

Another five elections resulted either in small losses or gains by the president’s party — 2002 (+8 seats), 1998 (+5 seats), 1990 (-8 seats), 1986 (-5 seats) and 1962 (-4 seats). The remaining two outcomes were between the two extremes, with the president’s party losing 15 seats in 1978 and 12 seats in 1970. (Midterm numbers come from “Vital Statistics on Congress: 2001-2002— by Norman J. Ornstein, Thomas E. Mann and Michael J. Malbin.)

Clearly then, midterm results over the past 50 years have generally fallen into one of two ranges — either small, single-digit changes (even sometimes in the favor of the president’s party) or large swings of at least two dozen and sometimes close to four dozen seats against the president’s party.

“Averaging— the outcomes of these dozen elections exaggerates the importance of the years with the biggest swings (1994, 1974 and 1966), ignores the bimodal distribution of election outcomes and produces a number that doesn’t come close to reflecting what has actually happened in the elections.

To be sure, the general trend that the president’s party loses seats in midterms certainly is worth noting, as is the fact that in only two of the past six midterms has the president’s party suffered anything more than single-digit losses. Indeed, in two of the past three midterms, the president’s party has gained seats. So we should expect Democrats to gain a handful of seats, shouldn’t we? Obviously not.

Each election, even each midterm, is different. The GOP is now down to 178 seats in the House, far below what it was just six years ago and back to where it was before the 1994 midterm surge vaulted Republicans into the majority. After back-to-back strong Democratic victories in 2006 and 2008 — when the party gained 50 House seats — the GOP is due to rebound, especially with Democratic President Barack Obama in the White House.

But the president’s continued popularity, the damage to the Republican brand, and the Democrats’ financial advantage limit the snapback that the GOP and the National Republican Congressional Committee can expect. Moreover, the noteworthy scarcity of House Democratic retirements so far and decisions by a few Republicans in Democratic-leaning districts to seek higher office give Democrats and the DCCC the opportunity to minimize overall losses.

Since we can’t know what shape the country or the economy will be in next fall, we can’t know whether Republicans will have a robust rebound or a modest one. But the evidence so far suggests a small 5- to 10-seat Republican rebound is more likely than anything substantial, and, at this point, a 30-seat Republican gain looks like a pipe dream. Of course, ruling out any specific outcome 15 months before the election is unwise.

Voters are increasingly concerned about the Obama agenda and the performance of the Democratic Congress, so a larger GOP gain than the one now likely certainly could occur. But right now, most GOP political strategists say they would be thrilled with a net gain of a dozen seats in the House, though they expect a somewhat smaller number. A 15-seat GOP gain would cause a wild celebration among savvy Republican operatives.

As for Democratic efforts to limit the party’s House losses to “just— 10 seats, as the DCCC has said, that’s a reasonable and a realistic goal. Anything much above that would be a surprisingly good year for the NRCC. Of course, during the rest of this year and next, expectations can and will change. Just don’t let anyone fool you into thinking that history forecasts a big Republican sweep. It doesn’t.
