Gallup's 6 Reasons The Election Turned Out Like It Did

What happened in the 2018 election? Why did it turn out the way it did. The people over at the Gallup Poll give us 6 factors they believe affected the election. Here's what they said:

Here are six factors that help explain what happened this past Tuesday:

1. Views of President Trump Played a Key Role

The president's party usually loses House seats in midterms, and loses many more seats -- 37 on average -- when the president is unpopular, defined as being below 50% job approval.

This year, Trump's job approval rating was 41% just before the elections, broadly similar to the approval ratings for Bill Clinton in 1994 (46%), George W. Bush in 2006 (38%) and Barack Obama in 2010 (45%), midterm years when each president's party lost a majority in the House of Representatives. By contrast, when the president's party gained seats in 1998 and 2002, the president's final pre-election job approval rating was above 60%.

Trump was an unusually important factor in this election, reflected in the finding that both his supporters and his opponents said he made them more motivated than usual to vote. The 60% of registered voters who said they were sending either a positive or a negative message about Trump with their vote was the highest in Gallup's history of asking this question. Perhaps most critically, the 34% who specifically said they were voting to oppose Trump was consistent with anti-presidential fervor in 2014 and 2010, when Obama's party lost seats -- as well as the 31% voting to oppose Bush in 2006, before his party lost seats.

More than six in 10 Democratic and Democratic-leaning voters (62%) said they were sending a message of opposition to Trump, similar to the proportion of Republican and Republican-leaning voters who were doing the same against Obama in 2014 and 2010 (58% each).

2. Dissatisfaction With Congress Was High

Two Gallup measures of Americans' satisfaction with their congressional leaders supported the conclusion that 2018 was going to be a "change year."

Public approval of the job Congress is doing and the percentage saying their own member and most members of Congress deserve re-election were at the low end of the historical ranges before midterm elections.

These low levels of attachment to the current Congress help explain the overall turnover in House seats and may account for the difficulty that incumbent Democratic senators in reliably Republican states had in keeping their seats.

3. Good Economy Did Not Overcome Other Factors

The strong economy may have been a factor in mitigating Republican seat losses, but it certainly wasn't enough to prevent a Democratic victory in the House.

By objective measures such as unemployment and gross domestic product, the economy is doing well, and historically a strong economy has been beneficial to incumbent politicians. Gallup's consumer measures are also positive -- in fact, they are the best in almost two decades, although still not at the peak seen in 1999 and 2000.

A strong economy should boost a president's approval rating and, in turn, influence how well his party performs in the midterms. But Trump (and, by extension, the Republicans) has not received a great deal of credit for the economy. As of August, 50% approved and 47% disapproved of the president's handling of the economy. This was higher than Trump's overall approval rating of 42% in the same poll. It was also the highest of all Trump's issue approval ratings in August, but, for context, was still significantly lower than the 71% for Clinton in 1998.

Regardless, this muted regard for Trump's performance on the economy has failed to elevate his overall job approval rating, which has been static near the 40% level for most of his presidency.

Voters still identified the economy as one of the top three issues that factored into their vote in this election, although it was of much more importance on a relative basis to Republicans than to Democrats and independents, and of less importance to all voters than in recent election years.

4. Democrats Believed More Was at Stake, Were More Engaged Than Usual

Democrats may have been convinced that more was at stake in this election than was the case for Republicans. Democrats were more worried about the consequences of leaving both houses of Congress in the hands of Republicans than Republicans were worried about Democrats gaining control of one or both houses.

Perhaps as a result, Democrats were unusually engaged this year -- expressing high intention to vote, high enthusiasm about voting, and giving high levels of thought to the election.

5. High Turnout Benefited Democrats

This high Democratic engagement was borne out in extraordinarily high voter turnout for a midterm election, according to early reports on voter participation. High-turnout elections generally benefit Democrats, with the increased numbers bringing more Democrats to the polls to offset Republicans' usually higher participation rates.

6. Divided Government Doesn't Bother Americans

The prospect of a divided government over the next two years is not something the majority of Americans will see as a negative, given that 29% prefer that government be divided and another 35% say it doesn't make a difference or have no opinion.

Republicans, as might be expected, would have much preferred to keep control with one party (their party). In September, a record-high 59% of Republicans voiced a preference for one-party control.
