For schools, the longest period in history with a 50-50 U.S. Senate will likely be remembered for one thing 鈥� Democrats鈥� passage of a massive COVID-relief bill that provided $122 billion in federal funds for K-12.

On March 4, 2021, Vice President Kamala Harris cast a key tie-breaking vote from the Senate dais that allowed the $1.9 trillion pandemic recovery passage to move forward.

鈥淣obody can use scarcity as an excuse,鈥� said Charles Barone, vice president of K-12 policy with Democrats for Education Reform, a think tank, and a former Democratic staffer in the Senate. 鈥淭here won鈥檛 be any other packages like that for at least another decade.鈥�

With new senators expected to be sworn in Tuesday, the Senate reaches the end of an era. Democratic Sen. Raphael Warnock鈥檚 in Georgia concluded only the fourth time in history that the Senate was evenly split between the two parties. And even though Arizona Sen. Kyrsten Sinema has officially to become an independent, the way she votes isn鈥檛 expected to change much. That shifts the balance to 51-49 for the Democrats. By many accounts, the Senate make-up has worked in . He scored wins with the American Rescue Plan and a key known as the Inflation Reduction Act. He鈥檚 also seated than any president since John Kennedy. 

But for those who latched onto Biden鈥檚 broad education agenda, the past two years have been bittersweet. Despite delivering an unprecedented windfall for pandemic recovery, Democrats had to sacrifice other education proposals, like two years of preschool and funds to rebuild aging school buildings.

At first, having Democrats in control of Congress and the White House 鈥済ave people enough hope that they aimed high and tried to shoot the moon,鈥� Barone said.  

But it wasn鈥檛 long before Sen. Joe Manchin of West Virginia, a fiscally conservative Democrat, put up roadblocks that forced Majority Leader Chuck Schumer of New York and the rest of the party to scale back their ambitions. 

With a 50-50 Senate, there鈥檚 鈥渘o room for error,鈥� said Bethany Little, principal at EducationCounsel, a consulting firm.  

鈥淭he slightest change in the wind can snatch defeat from the jaws of victory,鈥� she said. There was momentum for the party after Biden鈥檚 election, but once that sense of urgency waned, 鈥測ou couldn鈥檛 get some really big agenda items that Democrats have wanted for a long time.鈥�

Those included major increases in funding for child care and pre-K, two years of free community college and the extension of a higher child tax credit that data shows by almost 30%. Little called those proposals 鈥済enerational shifts that were all on the table at once.鈥�

After nearly a year of negotiations with Manchin and multiple rewrites, Biden鈥檚 so-called Build Back Better plan emerged as the Inflation Reduction Act, a shadow of the original package. It passed 51-50 on Aug. 7, with Harris breaking another tie.

The vice president was also called on to tip the balance in favor of Catherine Lhamon to lead the U.S. Department of Education鈥檚 Office for Civil Rights. Republicans opposed her confirmation because of positions on issues such as school discipline and transgender students鈥� rights they see as examples of government overreach.

鈥楾he holy grail鈥�

Advocates for federal spending on school construction were especially disappointed when dedicated funding to repair and rebuild schools was dropped from spending bills in an effort to win Manchin鈥檚 blessing.

鈥淭his country would absolutely have gotten help for its aged school buildings if we had had a Congress able to deliver good policy,鈥� said Mary Filardo,  executive director of the 21^st Century School Fund, which focuses on modernizing the nation鈥檚 schools.

Biden鈥檚 original included $100 billion for school construction and repairs. When Democrats cut that provision, Filardo and education groups hoped it would resurface in Build Back Better. That didn鈥檛 happen. 

鈥淪chool Infrastructure is like the holy grail,鈥� Barone said. 鈥淚t always seems within grasp, and then it isn鈥檛.鈥� 

The loss of a dedicated funding bill means many districts are now using American Rescue Plan funds for major facility upgrades.

Ironically, the Education Department frowns on those decisions, issuing last month that 鈥渟trongly discourages鈥� districts from using the money that way.

鈥楾he future of public policy making鈥�

Even though Manchin helped rein in progressives on a few of their big-ticket priorities, that didn鈥檛 stop the GOP from portraying Democrats as a party on a spending spree.

鈥淲hat the Democrats have done is extraordinarily harmful to the future of public policy making,鈥� said David Cleary, Republican staff director for the Senate education committee.

Both the American Rescue Plan and the Inflation Reduction Act were the result of budget reconciliation, a process that allows the party in charge to pass legislation without any votes from across the aisle. Those multi-billion-dollar packages 鈥渞uined the opportunity to come together,鈥� Cleary said.

The Biden administration, he said, has taken the same approach in pursuing policies and actions bound to annoy Republicans.

The Education Department鈥檚 effort to undo what Cleary called former Secretary Betsy DeVos鈥檚 鈥渃hef鈥檚 kiss perfect鈥� Title IX regulation is one example. Biden鈥檚 proposed rule would extend protections against sexual discrimination and harassment to transgender students and, Cleary argues, roll back due process rights for those accused of sexual misconduct.

He also called Biden鈥檚 plan to forgive up to $20,000 in student loan debt per borrower 鈥渁n abomination鈥� that further divides Republicans and Democrats and sends the message that 鈥渘o one ever has to pay for education.鈥� The U.S. Supreme Court the fate of the plan next month.

Even though Democrats still control the Senate, the Republican majority in the House will change the dynamic when both chambers get to work this winter. 

Education Secretary Miguel Cardona, for example, could find himself facing increased scrutiny from the House education committee over issues such as districts鈥� spending of COVID relief funds.

鈥淭hey won鈥檛 be able to ignore [Republicans鈥橾 letters and hearing requests,鈥� Cleary said.

Legislatively, is expected to make much progress on their agendas. But that also means Sinema鈥檚 knack for 鈥� on issues such as infrastructure, and 鈥� could become more valuable if members want to get anything done. 

Following the school shooting in Uvalde, Texas, she used her relationships with Republicans to help Democratic Sen. Chris Murphy and Republican Sens. John Cornyn of Texas and Thom Tillis of North Carolina on gun control. The Bipartisan Safer Communities Act passed by a vote of 65 to 33 and provides roughly $2 billion for safety improvements, school climate initiatives and student mental health services.

鈥淪he鈥檚 deeply committed to the Senate as an institution,鈥� Cleary said. 

Like his former boss, Sen. Lamar Alexander of Tennessee, Cleary said Sinema is willing to chip away at her 鈥渂ig vision鈥� with smaller victories. That sets her apart from members such as Vermont progressive Sen. Bernie Sanders and conservative Republican Sen. Ted Cruz of Texas.

Their style, he said, is more like: 鈥淚 want what I want. You can鈥檛 have anything, and why am I not winning?鈥�
