As he campaigns for a Manhattan congressional seat against fellow Democrats twice his age, 38-year-old Suraj Patel harnesses the frustration of his generation toward those who have held office for decades.

In his telling, Representatives Jerry Nadler, 75, and Carolyn Maloney, 76, are part of a crop of Democrats who rose to power in the 1990s only to fail on issues ranging from guns to climate change and abortion. The redistricting process that merged their congressional districts offers a chance for new leadership, Patel says.

“If we keep doing the same thing over and over and expecting different result: That’s not just the definition of insanity,” he said. “That’s also the definition of incumbency.”

More than 1,100 miles to the west in the presidential testing ground of Iowa, Republican Jeremiah Bronson was also considering whether someone other than 76-year-old Donald Trump might carry his party into the future. Bronson expressed growing interest in 55-year-old Virginia Governor Glenn Youngkin.

“He seems to be on the same page with conservatives around the country,” Bronson, 39, said as he dined on barbecued pork sandwiches with a half-dozen other Story County Republicans.

In a nation faltering along seemingly every conceivable divide, there’s a shared desire among Democrats and Republicans for a new generation of political leadership. The conversation is most pronounced when it comes to the White House as Trump considers another campaign and President Joe Biden confronts skepticism about his ability to mount a re-election bid in 2024 when he is 82.

“There’s just a sense of like, that rematch between these two old guys seems ridiculous to people,” said Sarah Longwell, a Republican strategist who conducts almost weekly focus groups with voters across the country and political spectrum.

There are recurring calls for youth and change in US politics.

Bill Clinton’s appeal for a new generation of leadership helped him rise from governor of Arkansas to the first baby boomer president in 1992. In 2008, Barack Obama’s relative youth was an asset in his primary campaign against Hillary Clinton and during the general election against Arizona Senator John McCain.

More recently, Pete Buttigieg’s 2020 presidential bid gained traction with its focus on fresh leadership before being overtaken by Biden, viewed by many Democrats as the safer choice against Trump.

The dynamics have shifted since then, with some Democratic voters furious that Biden and leaders in Congress haven’t done more to protect abortion rights, respond more aggressively to a wave of mass shootings and address climate change.

A new Associated Press-NORC Center for Public Affairs Research poll shows 83 per cent of US adults say the country is on the wrong track. Only 36 per cent approve of Biden’s leadership overall, while 62 per cent disapprove. Polling from AP-NORC in recent months captured deepening pessimism among members of his own Democratic Party about Biden, the direction of the country and the state of the economy.

A January AP-NORC poll found just 28 per cent of those surveyed and 48 per cent of Democrats said they want Biden to run for re-election in 2024.

Julián Castro, a former Obama housing secretary and onetime presidential candidate, said there’s “no doubt” that members of his party are frustrated and that Democrats in Washington need to show a sense of urgency and produce results. In a telephone interview from the Texas Democratic Convention in Dallas, he said Democrats seemed energised.

“My immediate hope is that that angst and frustration is going to be channelled positively to turnout in November,” he said, referring to the midterm elections. “And then we’ll reckon with what’s beyond that when November happens.”

Biden has repeatedly insisted he will run for re-election. But should he decide to step aside, a host of younger Democrats could be in contention. They include Vice President Kamala Harris, who is 57. California Governor Gavin Newsom, 54 and Illinois Governor J.B Pritzker, 57, have garnered attention for their responses to the Supreme Court’s abortion ruling and mass shootings.

Some Democrats seeking office this year have been clear about their desires that a new generation take its place in politics.

Last month, the Democratic candidate for governor in South Carolina, Joe Cunningham, proposed not only term limits but also age limits for officeholders, saying it was time to end America’s “geriatric oligarchy” of politicians who are staying “in office way past their prime.”

To Cunningham, who recently turned 40, that includes the incumbent he hopes to oust in November, 75-year-old Republican Henry McMaster, who is the state’s oldest sitting governor. But Cunningham also said the proposal was intended to apply to Biden.

For Republicans, the most pressing debate often seems to focus less explicitly on age and more on whether the party should move on from Trump. That’s particularly true in the wake of hearings by the House January 6 committee that have drawn new attention to his desperate efforts to stay in office after losing the 2020 election.

Longwell, the Republican strategist, said the hearings seem to be having an impact even among Republican voters who are not watching the sessions or persuaded by them because they are a reminder of the tumult that has surrounded Trump.

“One of the things I hear coming up over and over again in the groups is that Trump has a lot of baggage and that there’s all these other stars, Republican stars, and maybe it’s time Trump should be like an elder statesman,” she said.

A number of figures from Trump’s world and outside it are seen as potential challengers in 2024. Trump and his associates are especially focused on Florida Goveror Ron DeSantis, who, at 43, is increasingly viewed as a younger heir to the former president’s brand of politics.

Other Republicans making increasingly overt moves toward a presidential run include Arkansas Sen. Tom Cotton, 45; former South Carolina Governor Nikki Haley, 50; Texas Senator Ted Cruz, 51; former Secretary of State Mike Pompeo, 58; and former Vice President Mike Pence, 63.

Pat Brady, the former chair of the Illinois Republican Party who is not a Trump supporter, said he thinks the “fever has broken” when it comes to Trump’s standing with the GOP.

“I think the combination of him just spending all his time, every speech, relitigating 2020. Voters typically look forward. They don’t look backward,” he said.

Brady said part of the frustrations the voters have with their political leaders is the age-related.

“When you look at the leadership, I’m old and those guys make me look young,” said 61-year-old Brady. “This is a vibrant youthful country, fundamentally, and we’ve got a bunch of old people running it.”
