HARRISBURG, Pa. (AP) — Barack Obama warned anxious Democrats on Saturday that abortion rights, Social Security and even democracy itself is at risk should Republicans seize congressional majorities next week. “Sulking and moping is not an option,” the former president said in Pennsylvania.

“On Tuesday, let’s make sure our country doesn’t get set back 50 years,” Obama told hundreds of voters on a blustery day in Pittsburgh. “The only way to save democracy is if we, together, fight for it.”

He was the opening speaker in a clash of presidents past and present in the battleground state as each party’s biggest stars worked to energize voters on the final weekend of campaigning before Election Day on Tuesday.

Obama was accompanying Senate nominee John Fetterman, the lieutenant governor who represents his party’s best chance to flip a Republican-held seat. Later Saturday, they were to appear in Philadelphia with President Joe Biden and Josh Shapiro, the nominee for governor.

Democrats are deeply concerned about their narrow majorities in the House and Senate as voters sour on Biden’s leadership amid surging inflation, crime concerns and widespread pessimism about the direction of the country. History suggests that Democrats, as the party in power, will suffer significant losses in the midterms.

Even before arriving in Pennsylvania, Biden was dealing with a fresh political mess after upsetting some in his party for promoting plans to shut down fossil fuel plants in favor of green energy. While he made the comments in California the day before, the fossil fuel industry is a major employer in Pennsylvania.

Sen. Joe Manchin, D-W.Va. and chairman of the Senate Energy and Natural Resources Committee, said the president owed coal workers across the country an apology.

“Being cavalier about the loss of coal jobs for men and women in West Virginia and across the country who literally put their lives on the line to help build and power this country is offensive and disgusting,” Manchin said.

Former President Donald Trump will finish the day courting voters in a working-class region in the southwestern corner of the state Dr. Mehmet Oz, the Senate nominee, and Doug Mastriano, who running for governor.

The attention on Pennsylvania underscores the stakes in 2022 and beyond for the tightly contested state. The Oz-Fetterman race could decide the Senate majority — and with it, Biden’s agenda and judicial appointments for the next two years. The governor’s contest will determine the direction of state policy and control of the state’s election infrastructure heading into the 2024 presidential contest.

Polls show a close contest to replace retiring Republican Sen. Pat Toomey.

Shapiro, the state attorney general, leads in polls over Mastriano, a state senator and retired Army colonel who some Republicans believe is too extreme to win a general election in a state Biden narrowly carried two years ago.

Obama acknowledged that voters are anxious after suffering through “some tough times” in recent years, citing the pandemic, rising crime and surging inflation.

“The Republican like to talk about it, but what’s their answer, what’s their economic policy?” Obama asked. “They want to gut Social Security. They want to gut Medicare. They want to give rich folks and big corporations more tax cuts.”

Obama and Fetterman hugged on stage after the speeches were over.

“Today, Dr. Oz is going to be standing with Donald Trump,” Fetterman quipped.

Obama’s appearance in Pittsburgh marked his first time campaigning in Pennsylvania this year, though he has been the party’s top surrogate in the final sprint to Election Day. Obama campaigned in recent days in Georgia, Michigan, Wisconsin, Nevada and Arizona.

As Biden’s approval numbers sag, the current president has been a far less visible presence in battleground states. He’s spending more time in Democratic-leaning states where he’s more welcome.

Biden opened his day in Democratic-leaning Illinois campaigning with Rep. Lauren Underwood, a two-term suburban Chicago lawmaker who is nn a close race.

In a speech, Biden ticked through several of his administration’s achievements, including the Inflation Reduction Action, passed in August by the Democratic-led Congress. It includes several health care provisions popular among elderly people and the less well-off, including a $2,000 cap on out-of-pocket medical expenses and a $35 monthly cap per prescription of insulin. The new law also requires companies that raise prices faster than overall inflation to pay Medicare a rebate.

“I wish I could say Republicans in Congress helped make it happen,” Biden said of the legislation that passed along party lines.

Yet his comments from the day before about the energy industry may have been getting more attention.

“It’s also now cheaper to generate electricity from wind and solar than it is from coal and oil,” Biden said Friday in Southern California. “We’re going to be shutting these plants down all across America and having wind and solar.”

Pennsylvania has largely transitioned away from coal, but fossil fuel companies remain a major employer in the state.

The White House has worried privately for weeks that concerns about Fetterman’s health might undermine his candidacy. Fetterman is still recovering from a stroke he suffered in May. He jumbled words and struggled to complete sentences in his lone debate against Oz last month, although medical experts say he’s recovering well from the health scare.

Obama addressed Fetterman’s stroke directly.

“John’s stroke did not change who he is. It didn’t change what he cares about,” he said.

Despite his lingering health challenges, Fetterman railed against Oz and castigated the former New Jersey resident as an ultrawealthy carpetbagger who will say or do anything to get elected.

“I’ll be the 51st vote to elimaite the filibuster, to raise the minimum wage,” Fetterman said. “Please send Dr. Oz back to New Jersey.”

Oz has worked to craft a moderate image in the general election and focused his attacks on Fetterman’s progressive positions on criminal justice and drug decriminalization. Still, Oz has struggled to connect with some voters, including Republican voters who think he’s too close to Trump, too liberal or inauthentic.

Trump’s late rally in Latrobe is part of a late blitz that will also take him to Florida and Ohio. He’s hoping a strong GOP showing will generate momentum for the 2024 run that he’s expected to launch in the days or weeks after polls close.

Trump has been increasingly explicit about his plans.

At a rally Thursday night in Iowa, traditionally home of the first contest on the presidential nominating calendar, Trump repeatedly referenced his 2024 White House ambitions.

After talking up his first two presidential runs, he told the crowd: “Now, in order to make our country successful and safe and glorious, I will very, very, very probably do it again, OK? Very, very, very probably. Very, very, very probably.”

“Get ready, that’s all I’m telling you. Very soon,” he said.
