Donald Trump’s approval rating has fallen into territory that historically signals political disaster for the president’s party.

That should be excellent news for Democrats.

But a veteran pollster has issued a far more unsettling warning: even with Trump weakened, Republicans unpopular and the country frustrated, voters are still not rushing toward the Democratic Party.

“At some point, Dems are going to have to grapple with the reality that in the face of all of Trump and Republicans’ manifest horribleness and incompetence, people aren’t rushing toward the Democrats,” Sarah Longwell wrote Sunday.

Then she identified what she sees as one major obstacle.

“If you think the DSA stuff is helping, you’ve never talked to a swing voter.”

Longwell, publisher of The Bulwark and a longtime Republican pollster, was responding to data shared by columnist Ronald Brownstein.

Brownstein noted that Trump’s approval rating had fallen below levels that preceded major midterm wave elections against both Republican and Democratic presidents.

Historically, an unpopular president can become an enormous burden for congressional candidates from his own party.

Voters use midterms to express dissatisfaction.

The opposition gains enthusiasm.

Independent voters break against the White House.

Marginal districts suddenly become competitive.

On paper, those conditions appear to be forming again.

Some political analysts have predicted that Democrats are well positioned to retake the House in November. Others have argued that their chances of winning the Senate are improving as Trump’s approval falls and Republican controversies multiply.

Yet Longwell warned that Democratic optimism may be hiding a much deeper problem.

Voters can dislike Trump without trusting Democrats.

They can believe Republicans are governing badly while still viewing the alternative as too ideological, too unfamiliar or too far left.

That gap between Republican weakness and Democratic appeal could determine control of Congress.

Longwell’s reference to the Democratic Socialists of America came amid several high-profile primary victories by candidates associated with the socialist left.

In June, longtime Colorado Rep. Diana DeGette lost her primary to Melat Kiros, a socialist challenger.

For progressives, such victories represent growing dissatisfaction with an aging Democratic establishment and a demand for bolder policies on housing, health care, wages and foreign policy.

For centrists, they raise fears that candidates capable of winning overwhelmingly Democratic districts may become symbols Republicans use against the entire party.

The debate immediately ignited a political firestorm.

Gary Kasparov, founder of Renew Democracy, argued that Trump’s repeated scandals and damaging policies might not be enough to defeat the right if Democrats are perceived as more dangerous by moderate voters.

“Trump is corrupt and responsible for a litany of policies that are making life worse for Americans,” Kasparov wrote.

But he warned that years in office had normalized Trump in the eyes of some voters.

Those voters may see him as familiar—even after everything that has happened—while viewing left-wing candidates as a greater uncertainty.

“And if enough independents and moderates stay home, the far right wins,” Kasparov added.

His argument reflects one of the most frustrating realities of modern politics.

Outrage does not always produce realignment.

Voters may disapprove of a president without supporting the opposition.

They may tell pollsters that the country is heading in the wrong direction and still remain undecided, disengaged or unwilling to vote.

That is the danger Longwell sees.

Democrats may be assuming that Trump’s failures will automatically send voters into their coalition.

But elections are not won solely because the other side is unpopular.

A party must also persuade people that it is competent, culturally familiar and capable of improving their lives.

Others pushed back strongly against the idea that democratic socialism poses a serious national threat.

Political writer Jaid Jilani argued that commentators were exaggerating the influence of the DSA.

“Outside of a few ultra-blue districts, there are barely any DSA electeds,” he wrote. “No normal person even knows what DSA is.”

That response identified another central dispute.

Are swing voters actually focused on socialist organizations and ideological labels?

Or are party strategists and political media projecting an insider debate onto an electorate more concerned about groceries, housing, health care and employment?

Most voters do not closely follow factional organizations.

They may not know which politicians are formally connected to the DSA.

But Republican campaigns do not need voters to understand the group in detail.

They need only connect Democratic candidates to words such as “socialist,” “radical” or “extreme” through relentless advertising.

That strategy has worked before, particularly among older voters, suburban moderates and communities with personal or family histories involving authoritarian socialist governments.

Jeb Fain, a strategist with the House Majority PAC, offered the centrist conclusion in a single sentence:

“We won’t beat Republicans by outcrazying them.”

The remark was clearly aimed at candidates and activists whose rhetoric may excite the Democratic base but alienate persuadable voters.

Progressives would reject the suggestion that advocating universal health care, stronger labor rights or affordable housing is comparable to Republican extremism.

They may also argue that cautious centrism has repeatedly failed to inspire turnout or address the economic pain that fuels right-wing populism.

From that perspective, the danger is not that Democrats are moving too far left.

It is that they offer voters too little reason to believe meaningful change is possible.

This conflict has defined the Democratic Party for years.

Moderates argue that national elections are decided by swing voters who dislike ideological extremes.

Progressives argue that elections are lost when working-class and younger voters see no meaningful difference between establishment candidates.

Both sides can point to evidence.

Centrist Democrats have won difficult races in competitive states.

Progressive candidates have generated enthusiasm and defeated entrenched incumbents.

But the 2026 midterms will test whether those factions can coexist inside a coherent national message.

Trump’s weakness creates an opportunity.

His administration faces criticism over war, economic pressure, immigration enforcement and attacks on democratic institutions.

Republicans are struggling with internal divisions and an unpopular legislative agenda.

Under ordinary circumstances, the opposition party would be preparing for sweeping gains.

But Longwell’s warning suggests the political environment may no longer follow ordinary rules.

Trump has been the dominant figure in American politics for more than a decade.

Many voters who once found his conduct shocking now treat it as background noise.

Scandals that might have destroyed another politician are absorbed into a familiar cycle of outrage, denial and distraction.

That normalization gives Republicans a strange kind of protection.

Democrats cannot simply remind voters that Trump is dangerous.

Most Americans already have a firm opinion about him.

They must explain what they would do differently, how those policies would improve ordinary lives and why their candidates can be trusted to govern.

The challenge is especially difficult because the party is fighting on two fronts.

It must motivate progressives who want structural change while reassuring moderates who fear ideological upheaval.

It must condemn Trump without making every race solely about Trump.

And it must turn public dissatisfaction into votes rather than assuming anger will organize itself.

Brownstein’s numbers may still point toward a Democratic wave.

Trump’s approval could continue falling.

Economic or foreign-policy crises could deepen Republican vulnerabilities.

But Longwell’s warning has pierced the optimism surrounding those forecasts.

A weak president does not guarantee a strong opposition.

Republicans can lose public confidence without Democrats gaining it.

And unless the party understands that distinction before November, the blue wave Democrats expect may arrive as little more than a ripple.
