Three months before America decides its next commander-in-chief, the Potomac Nationals are staging a mock presidential election at Pfitzner Stadium with official voting booths, ballot boxes and a staple of most successful minor league baseball promotions — bobbleheads.

As part of the P-Nats’ effort to Make Voting Fun Again, all fans of legal voting age at Potomac’s game against Myrtle Beach on Sept. 3 will have the opportunity to cast their vote for Democratic nominee Hillary Clinton, Republican nominee Donald Trump or an “Other Candidate.” P-Nats mascot Uncle Slam might be just the unifying independent candidate this country needs. The Prince William County Office of Elections will be at the game to provide information about voter registration, absentee voting and what will appear on the ballot in November.

“We’re expecting all eligible fans to vote, but what may be even more important is that the voters of Northern Virginia, Washington, D.C. and its suburbs will have an opportunity to be part of a polling event that may be the most meaningful indicator of what the results will be in the 2016 presidential election,” P-Nats Chairman/CEO Art Silber said in a team release.

National polls now show Trump trailing Clinton by as many as 10 points.

All fans who cast a vote in the official voting booth on the concourse by the end of the fifth inning will receive an “I Voted” sticker, a commemorative “Proof of Vote” voucher and a raffle ticket for a signed Stephen Strasburg camouflage jersey. The team is also providing an incentive to get to the polls, which open at 5 p.m., early. The first 2,000 fans who bring their “Proof of Vote” voucher to one of several designated tables inside the ballpark will receive their choice (while supplies last) of a Clinton or Trump bobblehead featuring “real hair.” There will be 1,000 bobbleheads of each candidate available.

The game will feature a military flyover, presidential trivia and red, white and blue concession items. Prince William County government officials will throw ceremonial first pitches from the box seats, as opposed to the mound, in a nod to the tradition that began with William H. Taft in 1910. Silber will announce the election results on the field after the game.

As for those bobbleheads, Trump’s hair has never looked better.
