How Fear and Loathing Pushes Americans to Vote for Scandalous Candidates

Every election cycle sees its share of controversial, scandal-plagued candidates running for office. But the 2026 midterm elections will feature two such candidates – one from each party – in two of the highest-profile U.S. Senate races.

In Texas, the state’s attorney general, Ken Paxton, recently secured the Republican Party’s nomination over incumbent Sen. John Cornyn.

Cornyn and others have insisted that Paxton’s substantial legal and personal baggage – including corruption and bribery accusations that got him impeached by the GOP-led state House of Representatives – might lose Republicans a seat they’ve held for decades.

Democrats in Maine, meanwhile, have nominated Graham Platner, a political novice whose grassroots campaign and brash communication style propelled him to a decisive victory over the state’s Democratic governor, Janet Mills, who remained on the ballot but suspended her campaign in April.

This, despite Platner facing a series of personal scandals ranging from alleged sexual misconduct to a tattoo that turned out to be an emblem of Hitler’s paramilitary Schutzstaffel, or SS. Platner has claimed he was unaware of the symbol’s origins and has since covered it up.

Both Paxton and Platner won resounding victories in their primaries over more establishment candidates who were comparatively free of scandal.

As a scholar who studies Congress and elections, and the co-host of a podcast about political scandals, I believe political science offers answers about how Paxton and Platner pulled off victories in their states’ primaries – and why they might win in November.

Historic distance and distaste between the parties

Both Paxton’s and Platner’s flaws were well known prior to primary voting.

Early polling indicates that most of Texas’ Republican voters are likely to back Paxton in November. Polling also shows that Platner will continue to consolidate his party’s support in Maine.

Both parties’ leadership in Congress and beyond have also rallied behind their respective candidates. And both parties have used the opposing candidate’s scandals against them in the campaign, despite propping up flawed candidates themselves.

These actions can coexist thanks to two forces that political science has much to say about, precepts that have been steadily increasing in relevance over the past few decades: party polarization – or the distance between the two parties – and negative partisanship, voters’ tendency to vote based on negative feelings toward the other party.

Democrats and Republicans are far away from each other on policy preferences, issue positions and culture. They are also distant in terms of where they live, whom they support, how they feel and even whom they love.

Political science tells us that this polarized distance has increased feelings of personal animus between members of the two parties. Political psychology says the more different Americans are from each other, the easier it is for them to not just disagree with the other side but to dislike the other side to the point of viewing them as a threat.

These are trends Americans frequently see reflected in public opinion studies, many of which use the “feeling thermometer” to ask respondents to rate their personal feelings toward a person or party on a scale of zero degrees, or coldest/most unfavorable, to 100 degrees, or warmest/most favorable.

In the late 1970s, the average voter in each party was more or less neutral toward the opposing party, with scores hovering just below 50 degrees. By 2024, the average voter sentiment toward the other party had plummeted to 19 degrees.

In 1978, only 9% of Democrats and 7% of Republicans had a very negative opinion of the opposing party. By 2024, vast majorities in both parties – 64% apiece – reported such negative opinions.

Political science also tells us that these negative feelings about the other party are not simply prevalent. They are the driving force behind many voters’ election choices.

In other words, Americans are increasingly making voting decisions based not on who should win elections but rather on who shouldn’t. The opposing party is not just the less preferred option – it’s a threat that must be stopped at all costs.

When feelings about the other side are this negatively polarized, then winning – even with a less-than-ideal candidate as your standard-bearer – becomes more crucial than ever.

In fact, researchers have found that scandals involving candidates in a voter’s own party trigger a “defensive partisanship” that increases their hostility toward the other side. That is, scandals in a voter’s own party can make them more – not less – loyal to their team.

The higher the stakes, the lower the standards

Polarization and negative partisanship are not the only factors at work. The tight competition for control over major political institutions such as Congress and the presidency have raised the stakes of elections higher than ever. And, in the process, it has lowered standards for whom Americans are willing to support.

In her 2016 book, “Insecure Majorities,” political scientist Frances Lee found that partisan control over the federal government is more in question now that it has been in over a century. Lee says that closely fought elections that determine control of government help explain changing governing strategies in Congress.

But Lee’s findings also help explain our choices in elections and how – even in closely fought, high-profile races such as the 2026 Senate contests in Texas and Maine – voters end up nominating such blemished candidates.

In theory, closely fought competition should drive a “race to the top” in terms of candidate selection. Because control over institutions rests constantly on a knife’s edge, Americans might expect both sides to put forward their best, brightest and most electorally compelling candidates to try to win.

But thanks to polarization and negative partisanship, it isn’t always so. Instead, hard-fought elections among a closely divided electorate mean that individual votes matter more; that power hangs by a thread; and as a result, that one’s personal and political enemies are inches away from controlling the government.

Thus, closely divided elections only raise the stakes of one’s vote, along with the cost of defecting from your party’s candidate, however flawed they might be.

The lesser of 2 evils?

Voters constantly report feeling the need to “hold their noses” and vote for the “lesser of two evils.” The alternative – the other party taking power – is too grave to permit a truly principled stand. As a result, the race to the bottom continues, because the other side will always be worse.

These trends can help explain why, for example, Republicans circled the wagons around Donald Trump in 2016 despite his many scandals and serious misgivings within the party. They also illustrate why Democrats rallied around Joe Biden well into 2024, even as serious questions were raised about his physical age and mental fitness for office.

Whether Paxton’s or Platner’s partisan voters end up coalescing around them despite their scandals remains to be seen. Regardless, the reappearance of such imperfect candidates each cycle tells a bitter story about what voters will put up with to win.
