(NewsNation) — NewsNation/Decision Desk HQ has called the Pennsylvania gubernatorial race for Democrat Josh Shapiro.

Shapiro defeated Republican state Sen. Doug Mastriano, a retired U.S. Army colonel who drew controversy after being present at the Jan. 6 Capitol attack and echoing former President Donald Trump’s widely discredited claims of voter fraud.

Decision Desk HQ also called the state’s U.S. Senate race for Democrat John Fetterman.

All eyes were on Pennsylvania as the critical races in this battleground state decide which party will hold power in the U.S. Congress. 

The fight between celebrity doctor and Republican Mehmet Oz and Pennsylvania’s Democratic Lt. Gov. John Fetterman had come into the spotlight as they went head-to-head for GOP Sen. Pat Toomey’s seat after he decided not to seek re-election.

The two clashed on issues including abortion, fracking and crime in their debate as each of them sparred to get an edge over the other. 

Oz called Fetterman to concede the race Wednesday.

Additionally, NewsNation/Decision Desk HQ called the state’s 17th District congressional seat for Democrat Christopher Deluzio.

The outcome of Pennsylvania’s races will likely disrupt the partisan balance of the U.S. Senate. Of the 100 Senate seats, 35 will see elections during the midterms, including one special election. Democrats have the effective majority with Vice President Kamala Harris as the tie-breaking vote in the 50-50 split chamber. 

All 435 House seats are also up for election. Midterm election results will determine which party has legislative control, ultimately determining who sets the agenda for President Joe Biden’s remaining years in office.
