Republican Mehmet Oz and Democrat John Fetterman have cast their ballots Tuesday in Pennsylvania’s hotly contested Senate race. 

The showdown between Oz, a former daytime television host, and Fetterman, the current lieutenant governor of Pennsylvania, was deemed a toss-up in Fox News’ power rankings heading into election day.  

"I'm very proud of how I've run this campaign. Pennsylvanians are sending a very clear message to Washington -- we want less radicalism, and more balance," Oz told a group a reporters that had gathered Tuesday after he cast his ballot at Bryn Athyn Borough Hall in Huntington Valley, north of Philadelphia. 

"So I encourage everyone to vote, it's your duty," Oz added.
