CUYAHOGA FALLS, Ohio -- Rick Santorum's home-stretch schedule in Ohio will put him on stage election eve in a congressional district where he failed to file a slate of delegates.

The former Pennsylvania senator, who according to the Ohio Republican Party enters Tuesday's primary with a 29 percent delegate deficit, plans to rally Monday evening in Cuyahoga Falls.

Santorum will be at the Pavilion at Falls River Square on Front Street, which sits inside the

.

The 13th, which also includes Youngstown and a portion of Akron, is one of three districts where Santorum failed to run any delegates. In six others, Santorum has filed incomplete slates, according to

.

Each of the state's 16 congressional districts awards three delegates to its winner, making the 48 district-level delegates the biggest chunk of delegates at stake in Ohio's primary.

A total of 66 delegates are up for grabs here. Fifteen delegates are awarded at-large, proportionally, based on the statewide popular vote. Three others are unbound Republican National Committee delegates who do not have to commit until the summer convention.

Santorum's campaign also announced Saturday that he will hold a primary-night party in Steubenville, which is in the 6th District, another area where he failed to account for a single delegate.

Asked about the choices, Santorum spokesman Hogan Gidley told The Plain Dealer: "I thought in Ohio if you won a congressional district you won all the delegates there."

That would be true had Santorum's campaign submitted delegate slates there. Regardless, the campaign is chalking up the potentially devastating blunder to spotty organization late last year, when all efforts were focused on Iowa -- Santorum ultimately won the caucuses there -- and the candidate was still a long shot.

"The attempt by the establishment to to deceive the voters of Ohio and further their hand picked candidate will be met with resistance on Tuesday," Gidley said in an emailed statement. "I want to be clear, Rick Santorum's name will appear on every ballot in the state of Ohio and every vote cast will go towards his at-large delegate allocation.

"As it relates to individual Congressional Districts, its clear we aren't the establishment hand picked candidatee and back in December we were a small effort focused on Iowa. Now that we've won several states obviously much has changed and we feel confident that we will do well in both the delegate and popular vote count on Tuesday."

The campaign of Santorum's chief rival in Tuesday's primary, former Massachusetts Gov. Mitt Romney, has been unrelenting since learning of what they are calling "the delegate debacle." In a conference call with reporters Saturday afternoon, Ohio supporters and national counsel Ben Ginsberg dismissed Santorum as an candidate lacking the organizational chops to beat President Barack Obama in November.

Ballot access "is really is a true test whether a candidate ready for prime time," Ginsberg said. "Rick Santorum flunks that test."
