Joseph B. Scarnati III (born January 2, 1962) is an American politician from the U.S. State of Pennsylvania. He is a member of the Republican Party and is currently the President pro tempore of the Pennsylvania State Senate. Scarnati is in his fourth term as Senator from the 25th District.
As President Pro Tempore, he assumed the role of Lieutenant Governor upon the death of Catherine Baker Knoll on November 12, 2008.  He was sworn in on December 3, 2008.  He did not seek election to the post in 2010, and was succeeded as Lieutenant Governor by Jim Cawley.
In 1996, Scarnati first ran for Pennsylvania's 25th senate district when incumbent Republican State Senator John E. Peterson decided to retire in order to run for congress. Scarnati lost the Republican primary to Bill Slocum by 351 votes. Slocum won the primary with a plurality of 32% of the vote in the four candidate field. 
In 2000, Slocum was convicted of illegal dumping and resigned.  Scarnati ran for the seat as an independent against Slocum, who was attempting a comeback in the special election to replace him. Scarnati won the election with 33% of the vote, defeating Democratic nominee Joseph J. Calla (33%) and Republican nominee Bill Slocum (32%). He edged Calla by just 197 votes. After the election, he switched back to the Republican party.  
In 2004, Scarnati ran for re-election with no Democratic opposition in his first re-election campaign. He defeated Constitution Party nominee Alan R. Kiser 90%-10%.  In 2008, he won re-election to a third term, defeating Democrat Donald L. Hilliard 67%-33%.  In 2012, he won re-election to a fourth term unopposed. 
In May 2006, Robert Jubelirer and David Brightbill, the Republicans' two top leaders were defeated in the primary election, victims of the legislative pay raise fallout. Scarnati narrowly won the race to replace Jubelirer against veteran lawmakers Stewart Greenleaf and Jeffrey Piccola. 
Upon the death of Lieutenant Governor Catherine Baker Knoll on November 12, 2008, Scarnati assumed the position of Lieutenant Governor of Pennsylvania. He served as acting Lieutenant Governor until he was sworn into office on Wednesday, December 3, 2008.  He did not seek election to the post in 2010, and was succeeded as Lieutenant Governor by Jim Cawley.
Scarnati played a lead role in representing Republicans during Pennsylvania's 2009 budget impasse, and harshly criticized Governor Rendell's leadership style and priorities.  He was seen as "the de facto opposition leader to Rendell." 
When Chris Abruzzo was nominated to become secretary of the Pennsylvania Department of Environmental Protection in December 2013, and came under criticism for testifying that he was unaware of evidence that global warming was harmful to the environment, Scarnati defended Abruzzo, saying "We should not be deemed unfit to serve simply because we may not agree entirely with the strongly held view of some in this chamber and elsewhere. As a matter of fact, anyone who has ventured outdoors the past few days may very well have good reason to disagree with that point of view." It had been snowing in Harrisburg, off and on, for the previous two days. Scarnati was criticized by state senator Daylin Leach for equating weather with climate.  Abruzzo was confirmed in a 42–8 vote.
On January 22, 2018, the Supreme Court of Pennsylvania, divided along partisan lines, invalidated the state's congressional map, on the grounds that Pennsylvania's Republican-dominated legislature had engaged in partisan gerrymandering that "clearly, plainly and palpably" violated the Pennsylvania Constitution.  A week later, Scarnati formally declared his intent not to turn over any data requested by the Court's orders, maintaining a position Republicans petitioned to the U.S. Supreme Court, that the state's constitution delegates the role of congressional districting to the General Assembly.  On February 5, 2018, U.S. Supreme Court Justice Samuel Alito rejected the Pennsylvania Republicans' request for a stay and review of the state court's ruling. The top federal court's order was expected by many, as the state supreme court is the highest authority on matters based exclusively on the state constitution. 
Ex-Officio Member of all Senate Committees
Scarnati grew up in an Italian-American family in Brockway, Pennsylvania. He began his political career on the Brockway Borough Council in 1986. He helped run the family's restaurant and became the chairman of the Jefferson County Republican Party. Scarnati resides in his hometown of Brockway with his wife Amy. They enjoy spending time outdoors, cooking, traveling, biking and spending time with their children, Lisa, Kelly, Sawyer, Coll and Michael.
